ABSTRACT:
Composite layered solid or semi-solid state polymeric electrolytes which contain at least a first layer which is a tough, mechanically strong adhesive layer which is non-reactive with alkali metal and preferably polyalkylene oxide based such as PEO, which is applied to an anode, and a second layer applied to a cathode which is a moist, adhesive layer which may be reactive with alkali metal, is loaded with aprotic liquids and alkali metal salts which activates the first layer and maintains the cell integrity.
