description PURPOSE:To preclude hazard of firing from a battery when it is overcharged, by adding halides to electrolyte or into a positive electrode. CONSTITUTION:At least one sort of halide selected among halides of alkali metal, alkali earth metal, tetraalkylammonium, and alkyl is added to electrolyte or into a pos. electrode in an amount of 0.002-0.2mol/l. As this halide is reproduced in neg. electrode even after consumed in the pos. electrode, continued safety can be maintained. Added halide of the same metal as the neg. electrode is favorable because it does not react with the neg. electrode-e.g., LiCl, LiBr, etc., shall be preferred because of its large dissolusiveness in electrolyte. Thus hazard of firing even in the event of overcharging is precluded to accomplish a secondary battery with high safety.
