PURPOSE:To obtain a nonaqueous battery which has great battery capacity and voltage by making electrolyte contain at least one kind from phosphorous compounds expressed by specific formulas by specified amounts. CONSTITUTION:Electrolyte contains at least one kind of phosphorous compound, which is selected from groups of formulas I, II, and III, by 0.01wt.% to 5wt.%. Among the formulas I and II, R1 to R6 show alkyl groups, where carbon is not less than 4 and not more than 30, anyl groups, alkyl groups, aralkyl groups, or alkyl halide groups. Among the formula III, R<7> shows alkyl group, where carbon is not less than 1 and not more than 30, anyl group, alkyl group, aralkyl group or alkylhalide group, and R8 and R9 shows alkyl groups, where carbon is not less than 4 and not more than 30, anyl groups, alkyl groups, aralkyl groups or alkyl halide groups. By using such nonaqueous electrolyte, impregnating ability becomes excellent, and battery capacity can be increased. |
