ABSTRACT:
An electrochemical cell is made with two asymmetric electrodes and a solid polymer electrolyte. The anode is made from materials such metal hydrides, metals, metal hydroxides or metal oxides. The cathode is made from metal hydrides, metals, metal hydroxides or metal oxides. A solid polymer electrolyte is in intimate contact with and situated between the anode and the cathode. The solid polymer electrolyte is made from a polymeric binder such as polyethylene oxide, polyvinylalcohol, polyvinyl acetate, polyacrylamide, poly(vinylpyrrolidone), poly(2-vinylpyridine), poly(4-vinylpyridine) and polyethyleneimine. The polymeric binder has H.sub.2 SO.sub.4 or H.sub.3 PO.sub.4 dispersed within it.
