Rechargeable galvanic lithium cell

摘要

Nontoxic, chemically stable lithium tris(fluorosulphonyl)methanide, LiC(SO2F)3, is used as a conducting salt for rechargeable lithium cells containing nonaqueous electrolytes based on esters or polymeric electrolytes such as polyethylene oxide. The cell electrolyte is preferably comprised of an approximately 1 molar solution of the salt in a mixture of 50% by volume of ethylene carbonate (EC) and 50% by volume of diethyl carbonate (DEC).
