PURPOSE:To obtain a battery having high discharge voltage in high rate discharge and large capacity by using oxyharide as positive active material and adding gallium chloride as electrolyte to oxyharide. CONSTITUTION:In a nonaqueous battery using oxyharide as positive active material, gallium chloride is added as electrolyte to oxyharide. For example, thionyl chloride is used as positive active material and thionyl chloride solution is prepared by adding gallium chloride to thionyl chloride. The thionyl chloride solution is poured into a battery case from an electrolyte pouring pipe 5 to activate a battery. A positive current collector 4 is formed by fixing acetylene black with Teflon binder onto an expanded nickel net. A negative electrode 2 is formed by press-bonding a lithium film to a nickel current collecting net. By using gallium chloride as electrolyte, polarization of a battery is remarkably reduced and capacity of the battery is increased. |
