Abstract
A method is disclosed for manufacturing a nonaqueous battery which includes a negative electrode containing lithium or a material capable of occluding and discharging lithium, a positive electrode containing an oxide of manganese or cobalt, and a nonaqueous electrolyte. In the method the nonaqueous electrolyte is treated with an oxide of the metal of the positive electrode before the nonaqueous electrolyte is assembled into the battery. The method provides a nonaqueous electrolyte battery having an improved self-discharge property.
