New batteries could be assembled from materials from Mars
NASA
When forced into small cracks, water can be used in unexpected ways. A new battery design that relies on tiny amounts of water trapped within layers of clay could eventually provide sustainable power in extreme places like Mars.
Vasily Artemov He and his colleagues at the Swiss Federal Institute of Technology built the battery using components similar to traditional batteries, including two negatively charged electrodes and a positively charged electrode. But instead of making these electrodes out of metal, they…
