Abstract
The composite electrolyte for use in a thin plate rechargeable lithium battery comprises a porous or microporous inert polymer separator laminate which carries another porous polymer containing a dissociable lithium compound, and the adherent polymer layers are impregnated with an organic liquid containing a lithium salt. The porous or microporous separator laminate may be a single polymer layer or a multiple polymer layer. The composite electrolyte is inserted between the electrodes of a rechargeable lithium battery. In another embodiment the porous polymer separator sheet has an adherent dissociable lithium compound containing polymer layer on each of its major faces.
