New supercapacitors could be assembled from Martian materials
NASA
When forced into small cracks, water can be used in unexpected ways. New battery-like devices that rely on tiny amounts of water trapped within layers of clay could eventually provide sustainable power in extreme places like Mars.
Vasily Artemov and his colleagues at the Swiss Federal Institute of Technology have built a supercapacitor, a type of energy storage device similar to a battery. The supercapacitor has components similar to a conventional battery, including two electrodes: a negatively charged electrode and a positively charged electrode. But instead of making these electrodes…
