摘要

PCT No. PCT/US93/09859 Sec. 371 Date Mar. 21, 1996 Sec. 102(e) Date Mar. 21, 1996 PCT Filed Oct. 14, 1993 PCT Pub. No. WO95/02314 PCT Pub. Date Jan. 26, 1995Solvent-free, lithium-ion conductive solid polymer electrolytes containing an amorphous polyacrylonitrile polymer and an ionizable lithium salt are disclosed. The solid polymer electrolyte is prepared using a method that produces a solvent-free amorphous polyacrylonitrile copolymer without causing nitrile cyclization or cross-linking reactions to occur.
