EXAMPLE - Anode pellet was formed using lithium containing titanium oxide (Li14Ti5O12) as anode active material, graphite, polyacrylic acid as binder and zinc as reducible metal in ratio of 90-X, X= 0.5):6:3:0.5. A cathode pellet was formed using silica as cathode active material and polyacrylic acid as binder in ratio of 45:40:15. Electrolyte liquid was prepared using lithium borofluoride dissolved in mixed solvent of ethylene carbonate and gamma-butyrolactone. The battery was produced by accumulating and sealing of anode and cathode unit, poured with electrolyte liquid. The resulting battery had excellent heat resistance with low capacitance deterioration.
