Taking Materials to Extremes
June 21, 2017
Lithium-air batteries are the Holy Grail in the worldwide quest for better batteries, because they can store energy at very high densities, at least in theory. On the downside, they suffer from high losses in energy conversion and other drawbacks. Ju Li’s MIT research group, however, has designed a novel sealed lithium-oxygen nanotechnology chemistry that overcomes many of these problems.
