ABSTRACT:
New lithium ion conducting materials comprise porphyrin rings. These materials function as sites through which the lithium ion passes. In one aspect of the invention, an electrolyte composition consists essentially of a major amount of a lithium porphyrin complex and a minor amount of a polymer binder. In another aspect, an electrolyte composition consists essentially of aligned and spaced lithium porphyrin complex rings, wherein alignment and spacing of the porphyrin rings is achieved through the use of ladder type polymers, comb-like polymers, or crystalline polymers.
