Stanford is experimenting with carbon coating for lithium batteries

Researchers at Stanford University published an article in Nature on the development of a more efficient lithium battery with a new carbon coating.

The announcement of the article states that the coating of the anode with a monolayer of bound amorphous hollow carbon nanospheres makes it possible to isolate lithium deposits and contributes to the formation of a stable interphase of a solid electrolyte. As a result, lithium dendrites are not formed to a practical current density of 1 mA / cm 2 , and the Coulomb efficiency (charge efficiency) increases to ~ 99% during more than 150 charging cycles. These are significantly better results than unmodified uncoated samples, which usually show rapid attenuation in less than 100 cycles.

One of the authors of the article, Stephen Chu, a former US Secretary of Energy, believes that mobile phones with such batteries will work two to three times longer, and electric cars will become cheaper. However, while this is a scientific development, so that before mass production is still far.
