The extraction of lithium for batteries, essential for the electric vehicle movement and renewable energy utilization, poses significant environmental risks. Nonetheless, innovative solar-powered techniques for generating fresh water and lithium might improve sustainability.
Currently, most lithium is sourced from subterranean salt lakes in the Andes. The brine undergoes a concentration process through evaporation in outdoor ponds for several months, followed by the extraction of lithium carbonate, which consumes a substantial amount of freshwater. Additionally, when salty water is removed from the reservoir, freshwater from the surrounding rock can trickle down to fill the gap, leading to a decline in the water table, highlighting the negative impact of mining on water availability.
Numerous research initiatives are exploring Direct lithium extraction methods that bypass field evaporation. A notable approach, developed by Yu Tang and her team at Lanzhou University in China, has successfully generated usable freshwater and allowed for recovery back into the underground aquifers.
The team utilizes the unique structure of manganese oxides, which exhibit two crucial characteristics: they can convert a significant amount of sunlight into heat and selectively bond with lithium ions.
In their method, a thin stream of salt or seawater flows over a layer of manganese oxide exposed to sunlight. As the sun heats the material, water evaporates and lithium ions adhere to the oxide. Once these layers are saturated, acidic solutions can extract the ions, enabling the reuse of the material.
This process operates within a sealed environment that captures and condenses evaporated water for collection. The research team has tested small prototypes that successfully completed five cycles of lithium adsorption and release, with the collected water meeting the World Health Organization’s drinking water standards.
According to Ugo Bardi from the University of Florence, Italy, the approach is “very clever.” He suggests it could potentially offer a more sustainable lithium source.
“The paper appears credible,” Bardi notes. “One possible concern could be the material’s stability. How many cycles can it endure under real-world conditions?”

Research indicates that administering lithium to mice with low brain levels reverses cognitive decline associated with Alzheimer’s disease. These findings imply that lithium deficiency could contribute to Alzheimer’s, and low-dose lithium treatments may have therapeutic potential.
Several studies have highlighted a relationship between lithium and Alzheimer’s. A 2022 study found that individuals prescribed lithium faced nearly half the risk of developing Alzheimer’s. Another paper published recently linked lithium levels in drinking water with a reduced risk of dementia.
However, as Bruce Yankner from Harvard University points out, hidden variables may influence these results. He suggests that other elements in drinking water, like magnesium, might also contribute to a lower dementia risk.
Yankner and his team assessed metal levels in the brains of 285 deceased individuals, 94 of whom had Alzheimer’s, and 58 exhibited mild cognitive impairment. The remaining participants showed no cognitive decline prior to death.
They discovered that lithium concentrations in the prefrontal cortex (a vital area for memory and decision-making) were about 36% lower in those without cognitive decline, and 23% lower in individuals with mild cognitive impairment. “I believe environmental factors, including diet and genetics, play a significant role,” states Yankner.
There’s another concerning aspect. In Alzheimer’s patients, amyloid plaques exhibited nearly three times more lithium than areas without plaques. “Lithium is sequestered by these plaques,” explains Yankner. “Initially, there’s a lithium intake disorder, and as the disease advances, lithium levels decline further due to its binding to amyloid.”
To further investigate cognitive effects, the research team genetically modified 22 mice to mimic Alzheimer’s symptoms and reduced their lithium consumption by 92%. After around eight months, these mice performed significantly worse on various memory assessments compared to 16 mice on normal diets. For instance, even after six days of training, lithium-deficient mice took approximately 10 seconds longer to locate a hidden platform in a water maze. Their brains also had about 2.5 times more amyloid plaques.
Genetic evaluations of brain cells from the lithium-deficient mice indicated heightened activity of genes linked to neurodegeneration and Alzheimer’s. These mice experienced increased encephalopathy, and their immune cells failed to eliminate amyloid plaques, mirroring changes seen in Alzheimer’s patients.
The researchers then evaluated various lithium compounds for their ability to bind with amyloid and found that orotium— a compound created through the combination of lithium and orotic acid— had the least propensity to be trapped in plaques. A nine-month treatment regimen with orotium significantly diminished amyloid plaques in Alzheimer’s-like mice and improved memory performance compared to regular mice.
These findings point toward the potential of lithium orotium as a treatment for Alzheimer’s. High doses of various lithium salts are already being employed to manage conditions such as bipolar disorder. “A significant challenge with lithium treatment in the elderly is the risk of kidney and thyroid toxicity due to high dosages,” notes Yankner. However, he mentions that the quantities used in this study were about 1,000 times lower than those typically administered, which may account for the absence of kidney or thyroid issues observed in the mice.
Nonetheless, clinical trials are crucial to gauge how low doses of orotium lithium might impact humans, says Rudolf Tansy at Massachusetts General Hospital. “The challenge lies in determining who truly requires lithium,” he adds. “Excessive lithium intake can result in severe side effects.”
The ITER project is an experimental fusion power reactor

Nuclear fusion holds the promise of nearly limitless energy, but achieving this goal requires the world to produce a significant amount of concentrated lithium fuel from the ground up.
“A major challenge is the concentration phase, where specific lithium types are concentrated,” explains Samuel Ward from Woodruff Scientific Ltd, a British firm dedicated to nuclear fusion. “There is currently no scalable solution capable of providing the fuel required for future fusion reactors.”
Lithium is essential for the most prevalent fusion technology being developed, which combines two forms of hydrogen to generate energy. Moreover, the rare lithium-6 isotope, constituting only 7.5% of naturally occurring lithium, is the most effective for sustaining the fusion process. Consequently, many fusion power projects depend on “enriched” lithium, increasing the lithium-6 content to over 50%, and occasionally as high as 90%.
Only one demonstration fusion plant is set to outpace experimental reactors by delivering net electricity to the grid. Ward and his team require between 10 to 100 tons of concentrated lithium to initiate and sustain operations. The emergence of a new demonstration plant is expected to heighten this demand.
The initial such plants are projected to be operational by around 2040, allowing time for the enhancement of lithium supplies. However, the enrichment strategy must accelerate—one report indicates that the current lithium-6 supply is nearly non-existent. The U.S. amassed stockpiles during the Cold War, producing approximately 442 tons of enriched lithium from 1952 to 1963 to support nuclear weapon fabrication. This process utilized toxic mercury, leading to environmental pollution that needed remediation for decades.
At present, low-purity lithium for fusion is transitioning from the scarce amounts of highly enriched lithium required for nuclear armaments, according to EGEMEN KOLEMEN at Princeton Plasma Physics Institute, part of the U.S. Department of Energy.
For early integration of power, researchers are advocating for a modernized, eco-friendly version of the enrichment process—yet it still relies on mercury. Last year, the German government allocated funds for a project aimed at advancing this form of lithium enrichment while improving cost-effectiveness. “We plan to launch the first concentration facility in Karlsruhe by 2028,” says Michael Frank, who is participating in this initiative at Argentum Vivum Solutions, a German consultancy.
“The only viable approach for supplying adequate lithium concentrate [in the] short and medium term relies on mercury-based methods,” asserts Thomas Giegalich from the Karlsruhe Institute of Technology in Germany, also a collaborator on the project. However, this type of method will not suffice for the extensive requirements of hundreds or thousands of commercial fusion reactors.
“There is broad recognition that mercury-dependent processes cannot sustainably support the widespread deployment of fusion energy,” states Adam Stein from the Breakthrough Research Institute, a research center based in California.
Various mercury-free concentration techniques are under exploration, but they are not yet suitable for immediate application. This is also the case with the UK’s Atomic Energy Agency, which is funding the development of a clean lithium enrichment process, including efficient lithium-6 separation through microorganisms.
“Given the current lack of demand and the need for further innovation, other techniques have yet to be demonstrated at a commercial level but must succeed,” says Stein.
Freshwater essential for lithium mining is found in parts of Argentina, Bolivia, and Chile, situated in the world’s “lithium triangle” on the Andean plateau, boasting half of all global lithium reserves.
A recent study in Communications Earth and the Environment revealed that available freshwater for lithium extraction in these regions is significantly lower than previously believed. With global demand for lithium expected to surge by 2040, this poses a challenge as it surpasses the limited annual rainfall supplying water to the dry lithium triangle.
Minimizing freshwater usage in the lithium industry is crucial to prevent disruption in mining activities. Extracting one ton of lithium requires approximately 500,000 gallons of water, which also sustains small indigenous communities and unique wildlife habitats in the region.
Water scarcity affects both the ecosystem and the industry in the lithium triangle, as lithium is a key component in batteries driving the global shift towards clean energy technologies. Despite the projected quadrupling demand for lithium batteries by 2030, delays in mining operations due to resource availability raise concerns about meeting this growing demand.
Freshwater plays a vital role in determining the supply of lithium available for mining in the lithium triangle. Rainfall washes lithium-rich minerals out of rocks, creating lagoons filled with lithium-rich water where mining companies extract the mineral. However, limited weather data and overestimation of freshwater supply in the region pose challenges to sustainable mining.
Research into water and resource availability for lithium mining operations is ongoing, emphasizing the need for a comprehensive understanding of the entire lithium supply chain. Studies in lithium-rich regions worldwide are essential to grasp the environmental and social impacts of lithium extraction.
Infinite power from nuclear fusion can be brought one step closer following the accidental discovery of a new process to supply isotope lithium-6, essential to providing fuel to sustainable fusion reactors.
The most challenging fusion process combines two isotopes of hydrogen, deuterium and tritium to produce helium, neutrons and many more energy. Tritium, a rare radioisotope of hydrogen, is difficult to procure and expensive. The “Breeder” reactor aims to produce tritium by bombarding lithium with neutrons.
Lithium atoms exist as two stable isotopes. Lithium-7 accounts for 92.5% of natural elements, with the remainder being lithium 6. The more rare isotopes react with neutrons much more efficiently and produce tritium in fusion reactions.
However, separating the two lithium isotopes is extremely difficult. Until now, this has been achieved on a large scale using highly toxic processes that depend on mercury. Environmental impacts have forced the process to be unemployed in Western countries since the 1960s, forcing researchers to rely on a decline in the stockpile of lithium-6 produced before the ban.
Sarbajit Banerjee Eth Zurich and his colleagues in Switzerland happened to discover alternatives while considering ways to clean water contaminated by oil drilling.
Researchers noticed that cement membranes containing lab-made compounds called Zeta vanadium oxide collect large quantities of lithium and appear to separate lithium-6 disproportionately.
Zetavanadium oxide contains tunnels surrounded by oxygen atoms, Banerjee says. “Lithium ions pass through these tunnels, which just happens to be the right size. [to bind lithium-6]”We found that lithium-6 ions bond more strongly and are retained within the tunnel.”
Researchers don’t fully understand why lithium-6 is preferentially retained, but based on simulations they believe it is related to the interaction between ions and atoms at the edge of the tunnel, says Banerjee.
He says he has not separated less than six grams of lithium to date, but he wants to expand the process to produce tens of kilograms of isotopes. Commercial fusion reactors are expected to require large amounts of elements every day.
“But these challenges become pale compared to the major challenges with laser ignition for plasma reactors and fusion,” says Banerjee.
A severe fire in a garage and home in south of Sydney may have been caused by a faulty lithium-ion battery in an electric scooter. Fire investigators discovered that this incident was part of a series involving lithium-ion batteries.
Another fire broke out at New Farm apartments in Brisbane city centre in early November, believed by authorities to be ignited by an electric scooter’s battery. In March, New South Wales experienced four battery-related fires in one day.
The New South Wales Fire and Rescue Service has identified lithium-ion batteries as the state’s fastest-growing fire hazard, responding to 272 battery-related fires last year. Fire authorities in Victoria and Queensland are responding to lithium-ion battery fires almost every day.
Lithium-ion batteries are widely used in various devices due to their fast charging, power density, and long battery life. Australia’s largest lithium-ion battery, the Victorian Big Battery, can power over one million homes for 30 minutes.
What are lithium-ion batteries used for?
Different types of lithium-ion batteries are used in various devices, and when operated correctly, they are considered safe.
Lithium-ion batteries power cell phones, computers, electric scooters, electric bicycles, and electric cars, providing quick energy delivery and long battery life.
Lithium-ion batteries can catch fire due to overheating and physical damage, reaching high temperatures and producing toxic gases.
Why do lithium-ion batteries catch fire?
Lithium-ion batteries contain lithium ions in an electrolyte, and charging them too quickly can cause thermal runaway, leading to a rise in temperature and potential explosion.
Battery quality matters, as physical damage, defects, and overcharging can contribute to battery fires. It is essential to use approved chargers and follow manufacturer guidelines.
To prevent battery fires, avoid overcharging, charge batteries on hard surfaces, and recycle old batteries properly to reduce the risk of fire incidents.
circleWhen Aleksandar Matkovic initially received a life-threatening message, he believed it was a prank. The message, sent to his Telegram account just after midnight on August 14, stated, “We’re going to chase you until you disappear, you bastard,”.
“Initially, I brushed it off as a joke, but then the next morning I received another message: ‘How’s the fight against Rio Tinto going?’ It came from an unfamiliar profile, and the app indicated the sender was only 500 meters away,” recounted Matkovic, a prominent activist involved in protests against proposed lithium mines in Serbia. “Keep away,” he added.
While in Split visiting a friend, Matkovic, who resides in Belgrade, felt as though he was being followed, especially given the recent mass protests against Rio Tinto’s plan to construct a $2.4 billion lithium mine in Serbia’s Jadar Valley.
“I scanned the area and thought, ‘What is happening?’ It was unsettling, contemplating the possibility of someone tailing me, so I reached out to my lawyer. Soon thereafter, I received a third, more menacing message,” he shared.
The third message, written in German, stated: “We are aware of your ties to the leaders of the uprising. It all commenced with you. Even if you commit a heinous act and vanish, we will hunt you down. However, you won’t be able to turn to the authorities for help, because you know it’s futile. Rest assured, if you value your life and freedom, stay out of the public eye for some time. Conduct yourself impeccably on social media. Understand that you must fear for your safety and that of your sibling.”
Following this, Matkovic reported the threat to Belgrade police, who are presently investigating the matter based on the threat and related documents seen by the Guardian.
This rapidly evolving situation is intricate and carries repercussions beyond the Belgrade prosecutor’s office.
The opposition to the lithium mine in Serbia has evolved into a focal point for societal discontent, uniting ultranationalists, environmentalists, leftists, and individuals concerned about economic ties with the West and the domestic environment. Groundwater contamination is a pressing issue.
Serbian President Aleksandar Vucic recently issued a warning, accentuating the reported plotting of a “color revolution” by the opposition in the Balkans.
Serbia, a former Yugoslav republic, boasts substantial lithium reserves crucial for electric vehicle batteries. The EU has committed to banning a minimum of 10% of critical minerals, including lithium, from European mining operations by 2030.
Julia Poliscanova, director of vehicles and supply chains at the think tank Transport and Environment, emphasized the necessity of lithium for European transport electrification. She stressed the importance of sourcing lithium sustainably and responsibly to support Europe’s transition towards electric mobility.
In response to the threats against Matkovic, Rio Tinto denounced violence, affirming, “Rio Tinto vehemently condemns any direct or implicit threats of violence, whether online or in person, against individuals engaged in discussions regarding the Jadar project.”
Rio Tinto employees have faced online threats and intimidation during local protests, highlighted a company spokesperson.
To safeguard himself and his family following multiple distressing emails, Matkovic has taken precautions, including seeking refuge at various European embassies in Belgrade. Additionally, he intends to request intervention from the UN Special Rapporteur on environmental activists.
“Since August 14th, my life has been a precarious blend of normalcy and turmoil,” Matkovic reflected. “How does this fit into our strategy for combating climate change? What does the green transition we aspire to entail if it necessitates violence?”
IIn the vast white desert of Salinas Grandes, 45-year-old Antonio Carpanchay raises an axe and chips away at the earth. He has worked the land since he was 12, splitting and collecting salt, replenishing it for the next season and teaching his children to do the same.
“Our whole indigenous community works here, even the elders,” he says, shielding his sunburned face from the sun. “We’ve always done it. It’s our livelihood.”
As his son watches warily, Karpanchai points north, to a pile of black stones and mud that stands out from the stark whiteness of the plains. “They started mining for lithium in 2010,” he says. “We made them stop because they were destroying the environment and affecting the water quality. But now they’re coming back, and I’m scared. We could lose everything we have.”
Antonio Carpanchay and his son mine and sell salt in Salinas Grandes, Argentina.
The Salinas Grandes are the largest salt flats in Argentina, stretching over 200 miles and containing a biodiverse ecosystem. Sitting in the Lithium Triangle The same goes for parts of Chile and Bolivia.
Lithium is a silvery metal known as platinum and is a vital element in batteries for mobile phones and electric cars. By 2040, global demand is predicted to increase more than 40-fold. But that exploitation has also raised moral debates, pitting the transition to green energy against the rights of local and indigenous peoples.
The sign reads “No to Lithium.”
Thirty-three indigenous communities in the Atacama and Cola regions, fearful of losing or polluting their water resources and being forced off their lands, have banded together for 14 years to try to halt the mining operations. “Please respect our territory” and “No to lithium” are scrawled on dozens of road signs, abandoned buildings, and murals.
But now, with more than 30 global mining conglomerates moving into the region at the instigation of “anarcho-capitalist” President Javier Milley, the battle lines are being redrawn. Offers of jobs and investment are increasingly dividing communities, with some already reneging on agreements and more expected to follow.
“Businesses are moving in,” Karpanchai said. “I worry about my grandchildren’s future.”
TThe biggest concern for indigenous peoples is water. Approximately 2 million liters of evaporation is required per tonne of lithium. This threatens to dry up the region’s wetlands and already dry rivers and lakes. Industrial-scale pumping also threatens to contaminate fresh groundwater, endangering livestock and small-scale agriculture. The impacts will likely reach farther than the immediate source of the water: as locals say, “water knows no borders.”
Clemente Flores, a 59-year-old community leader, says water is the most important part of Pachamama, which means “Mother Earth.” “Water nourishes the air, the soil, the pastures for the animals and the food we eat,” he argues.
“If we used all the water for mining, the salt flats would dry up. We need water to grow salt. Without salt, there are no jobs,” said Karpanchai, who relies on the freshwater resources to raise llamas and sheep. “Chemicals from mining could pollute the water and pastures. We could lose everything.”
Flavia Lamas, 30, a tour guide on the salt flats, remembers when lithium companies began exploring around 2010. “They said mining lithium would not affect Mother Earth, but then water became a problem. Water was running off the salt flats and after just one month our land started to degrade,” she says.
Flavia Lamas, who guides tourists through the Salinas Grandes salt flats, compares the mining companies to the Spanish colonial army of the 1500s.
According to Pia Marchegiani, director of environmental policy at the NGO: Environment and Natural Resources Foundation (Fern) Environmental assessments leave gaps in understanding the full impact of large-scale development. “This region is a watershed. Water comes from everywhere, but nobody is looking at the whole picture,” Marchegiani says. “You have Australians, Americans, Europeans, Chinese, Koreans, but nobody is adding up their water use.”
Wildlife within the ecosystem may also be affected. A 2022 study found that flamingosLithium mining in Chile is slowly killing off coral reefs that feed on microorganisms in seawater.
Communities also fear their land will disappear. Indigenous people consider the land sacred and ancestral, and have lived on it for centuries, but they worry they will be forcibly removed. “We can’t sacrifice our community land. Do you think that’s going to save the planet? Instead, we’re destroying Mother Earth herself,” Flores says.
A painting welcoming visitors to the village of El Moreno features an anti-lithium message.
youUntil recently, the 33 communities fought together as one, but over the past year, cracks have appeared as mining companies have offered economic incentives. “Companies are approaching,” Karpanchai said. “They approach us alone, they come in disguise. People are feeling the pressure.”
Lamas says mining companies are descending on the region like conquistadors in the 1500s. “The Spanish brought mirrors as gifts. Now the miners come by truck,” she says. “We’ve been offered gifts, trucks, and houses in the city, but we don’t want to live there.”
Marchegiani accuses the companies of deploying “divide and conquer” tactics. Alicia Chalabet, an indigenous lawyer from Salinas Grandes, says the community is under “constant pressure” to agree to the demands. “We’re flooded with lithium companies here. It’s increased a lot in the last five years,” said Chalabet, who is currently handling 20 cases. “The community is just an obstacle.”
The community of Lipan was the first to agree to let mining company Rishon Energy explore the waters beneath the saltwater in exchange for promises of jobs and essential services, but some residents say the decision was controversial, and some community members claim not all residents were allowed to vote.
A facility set up by Rishon Energy to explore lithium potential near the village of Lipan. The company claims to employ staff from the local area and invest in their training.
Rishon denies that its decision to mine in Lipan was controversial and says it complied with all regulations that require it to seek local community support in lithium exploration. The company has previously told reporters that it has invested in 15 secondary school and 15 university scholarships, provided computers to local schools, and hired 12 workers from Lipan.
Anastasia Castillo, 38, grew up in Lipan and now lives in a nearby commune. She says neither she nor her parents, who remain in the village, agreed. “I’m very sad. My children’s future is ruined. We have 100 cows and 80 llamas in the area, which is my main job. I’m afraid they’ll die,” Castillo said. “Now we’re separated.”
A device that can convert infrared light into visible light
Laura Valencia Molina et al. 2024
Glasses coated with lithium compounds may one day help us see clearly in the dark.
For more than a decade, researchers have been searching for the best lightweight materials that can convert infrared light, invisible to the human eye, into visible light in order to provide an alternative to night-vision goggles, which are often heavy and cumbersome.
Until recently, the leading candidate was gallium arsenide. Laura Valencia Molina The researchers, from the Australian National University in Canberra, and their colleagues found that a film of lithium niobate coated with a lattice of silicon dioxide performed better.
“Through improved design and material properties, we have achieved a tenfold increase in the conversion rate from infrared to visible light compared to gallium arsenide films,” the team said. Maria del Rocio Camacho MoralesAt the Australian National University.
Through a series of experiments, the team demonstrated that the lithium niobate film could convert high-resolution images from infrared light with a wavelength of 1,550 nanometers to visible light with a wavelength of 550 nanometers, exceeding the capabilities of gallium arsenide.
Night vision goggles require infrared particles called photons to pass through a lens and be converted into electrons in a device called a photocathode. These electrons then pass through a phosphor screen to be converted into visible light photons. This entire process requires cryogenic cooling to prevent distortion of the image.
Molina says the lithium niobate film is hit by infrared light emitted by an object and illuminated with a laser at the same time. The film combines the infrared light with the laser light, which then up-converts the infrared light into visible light.
Camacho Morales says that one day, lattices of lithium niobate and silicon dioxide could be made into a film thinner than plastic wrap that could be coated over regular glasses to improve night vision.
While still in the research stage, the laser was positioned so that it could be easily shone onto the film along with infrared light emitted by the object, and the team is now experimenting with creating an array of nanolasers that can be positioned on top of the lithium niobate film.
The research is an important next step toward lightweight night-vision devices, and perhaps a film that can be attached to ordinary glasses, Camacho Morales said. It could also help drones navigate in the dark, he said, because current night-vision devices are too heavy to carry in some vehicles.
Researchers test batteries using new materials designed by AI
Microsoft's Dan DeLong
Artificial intelligence can accelerate the process of discovering and testing new materials, and researchers have used that ability to develop batteries that are less dependent on the expensive mineral lithium.
Lithium-ion batteries power not only electric cars but also many devices we use every day. They will also become a necessary part of green power grids, as batteries will be needed to store renewable energy from wind turbines and solar panels. However, lithium is expensive and mining it damages the environment. Finding a replacement for this important metal can be expensive and time-consuming, requiring researchers to develop and test millions of candidates over years. Utilizing AI, nathan baker Microsoft and its colleagues accomplished this task in a few months. They designed and manufactured a battery that uses up to 70% less lithium than some competing designs.
The researchers focused on types of batteries that contain only solid parts, looking for new materials for battery components called electrolytes, through which charge is transferred. They started with 23.6 million candidate materials, designed by tweaking the structure of an established electrolyte and replacing some lithium atoms with other elements. The AI algorithm filtered out materials that were calculated to be unstable or have weak chemical reactions that make the battery work. The researchers also considered how each material behaved when the battery was actively operating. After just a few days, their list contained just a few hundred candidates, some of whom had never been studied before.
“But we're not materials scientists,” Baker says. “So I called the experts who have worked on large-scale battery projects at the Department of Energy and said, 'What do you think? Are we crazy?'
vijay murugesan He works at the Pacific Northwest National Laboratory in Washington state and was one of the scientists who answered the phone. He and his colleagues proposed additional screening criteria for AI. After further rounds of elimination, Murugesan's team finally selected one of his AI proposals and synthesized it in the lab. It was noticeable because half of what Murugesan expected to be lithium atoms were replaced with sodium. This is a very novel recipe for an electrolyte, he said, and the combination of the two elements raises questions about the fundamental physics of how the material works in batteries. Masu.
His team built a working battery using this material, albeit with a lower conductivity than similar prototypes that use more lithium. Both Baker and Murugesan said much work remains to optimize the new batteries. However, the manufacturing process took about nine months, from the time Murugesan first talked to his Microsoft team until the battery was functional enough to light a light bulb.
“The methodology here is cutting edge in terms of machine learning tools, but what really elevates this is that things have been created and tested,” he says. Rafael Gomez-Bombarelli from the Massachusetts Institute of Technology was not involved in this project. “It's very easy to make predictions. It's hard to convince someone to invest in an actual experiment.” He said the team will accelerate calculations that physicists have been making for decades, and It is said that AI was used to strengthen it. However, this approach may also encounter obstacles in the future. For this kind of work, he said, the data needed to train the AI is often sparse, and materials other than battery components may require more complex ways of combining elements. he says.
