Researchers directly visualize formation and disappearance of Li-O2 reaction products; insights to support development of rechargeable lithium-air batteries

Green Car Congress

During discharge, Li ions meet with reduced oxygen on the surface of the Li x V 2 O 5 electrode forming Li 2 O 2 , which is decomposed upon recharge. The rechargeable Li?air Kendall Associate Professor of Mechanical Engineering and Materials Science and Engineering at MIT and the senior author of the paper, says.

Researchers find synergy between lithium polysulfide and lithium nitrate as electrolyte additives prevent dendrite growth on Li metal anodes

Green Car Congress

Yet-Min Chiang (a co-founder of A123 Systems) at MIT, have discovered that a synergetic effect resulting from the addition of both lithium polysulfide and lithium nitrate to ether-based electrolyte prevents dendrite growth on Li-metal anodes and minimizes electrolyte decomposition. Researchers from SLAC and Stanford led by Prof.
