ABSTRACT:
A polymer electrolyte suitable for use in a lithium ion cell comprises polyvinylidene fluoride (PVdF) combined with a solution of a salt such as lithium perchlorate, in a compatible solvent such as an ethylene carbonate/N-methyl-pyrrolidone mixture. The PVdF is a homopolymer of high molecular weight, with a melt flow index at 230.degree. C. and 10 kg of less than 1.O g/10 min.
