Five different but novel superacid-based lithium salts were synthesized and characterized. The electrochemical stability of these salts was studied by cyclic voltammetry and the process ability was carried out by chemical techniques. Solid polymer electrolytes of these salts with different compositions were prepared with polyethylene oxide and polyacrylonitrile under anhydrous conditions and their conductivities were measured at room temperature. High voltage composite cathode films of lithium cobalt oxide were prepared with aluminum and stainless steel grid materials. Lithium/polymer electrolyte/lithium cobalt oxide cells of about 4 mAh capacity were fabricated and were used to conduct charge and discharge studies to evaluate these novel lithium salts based polymer electrolytes for lithium batteries. The initial discharge studies on these cells showed a maximum of 71% discharge efficiency with good voltage regulation.
