Abstract:

To meet the high-energy requirement that can enable the 40-miles electric drive Plug in Hybrid Electric Vehicle (P-HEVs), long range electric vehicle (EV) and smart grid, it is necessary to develop very high energy and high power cathodes and anodes that when combined in a battery system must offer 5,000 charge-depleting cycles, 15 years calendar life as well as excellent safety characteristics. These challenging requirements make it difficult for conventional cathode materials to be adopted in P-HEVs and EVs. Metal-air batteries, specifically Li-air battery, have large theoretical energy density about 2-10 times higher than those of lithium-ion batteries, and are frequently advocated as the solution toward next-generation electrochemical energy storage for applications including electric vehicles or grid energy storage. In this talk, I summarize the recent discovery on developing the Li-O2 battery, particularly highlighting the strategy of how to move this system from an open to a close configuration.
