日 時 : 平成23年7月4日(月)15:00~17:00
場 所 : 総合研究棟3階301講義室

講演内容 :  Aqueous Lithium-ion battery (LIB) may solve the safety problem of LIB using organic electrolyte, as well as the undesirable cycling life of the commercialized aqueous secondary batteries (Pb acid, Ni-MH), but all reported aqueous LIB systems behaved poor cycling stability. We have extensively studied the cycling ability of many positive and negative electrode materials in aqueous electrolyte, and found that the negative electrodes at discharged stated would react with H2O and O2, which mainly resulted in the capacity fading upon cycling. By eliminating O2, adjusting pH, and using carbon-coated electrode materials or activated carbon. The aqueous LIB offers high safety, low cost, long cycling life and appropriate energy density, and shows potential application for stationary power sources.
