Abstract

An electrochemical cell, comprising a lithium anode, a cathode, and a liquid electrolyte of lithium tetrachloroaluminate dissolved in thionyl chloride, has a coating of a Li ion conductive solid polymer electrolyte on the anode. An example of the solid polymer electrolyte is a Li salt complex of poly[bis(methoxyethoxyethoxy)phosphazene].
