Large lithium polymer battery development The immobile solvent concept

摘要: Abstract The program to develop large lithium-metal, polymer electrolyte batteries for electric traction and stand-by power is reviewed. Dry conductivity improvement through research into polymers lithijm salts has led a thin-film lithium battery that operates in the range of 60 40 °C. Recent developments cell design production are given, including preliminary results on US Advanced Battery Consortium (USABC). Results cycle-life tests small laboratory cells over several years also presented confirming electrolyte's exceptional stability rechargeable-cell environment.
