Researchers from the University of Illinois at Chicago and the US Department of Energy’s (DOE) Argonne National Laboratory has produced a design for a lithium-air battery that could have five times the energy capacity of today’s lithium ion batteries. “Others have tried to build lithium-air battery cells that run on air, but they failed because of little cycle life,” said Larry Curtiss, co-principal investigator and Argonne Distinguished Fellow. Previous battery cells tested in the lab required a separate supply of pure oxygen, requiring a tank of oxygen gas would have to be part of the battery system. A lithium-air battery that uses air from outside eliminates this problem.

Researchers at The University of Texas at Dallas believe they have made a breakthrough in the development of lithium sulfur batteries that could drastically lengthen battery life. Writing in Nature Nanotechnology, the team used molybdenum to create a sulfur-carbon nanotube material that provded more conductivity on one electrode, and a nanomaterial coating to create stability for the other. "Common lithium-ion batteries only have a certain capacity," said Dr. Kyeongjae "K.J." Cho, professor of materials science and engineering at the Erik Jonsson School of Engineering and Computer Science who led the research.
