ABSTRACT:
A composite solid electrolyte having a transference number above 0.5 for use in primary or secondary electrochemical cells. The solid electrolyte includes non-conductive oxide particles, of less than 5 microns in size, an alkali metal salt coating or in contact with these particles, an insulating elastomer forming a complex with the salt, and a solvent. Batteries and multi-cell batteries contain such solid electrolyte, and such batteries can be assembled with the cathod in the discharged state.
