Abstract

PURPOSE:To increase the effective surface area of a negative active material, and reduce the internal resistance of the said material by providing projections and indentations over the surface of the said material which touches a separator. CONSTITUTION:After a negative active material 5 made of a metallic simple substance such as lithium is pressed and fitted into a shallow negative terminal part 2 in a dry atmosphere, projections and indentations 10 are formed on the surface of the material 5 by means of a press-work equipment 20. Next, a separator 6 impregnated with electrolyte is connected over the surface of the projections and indentations 10, and the negative terminal part 2 and a positive can 1 packed with a positive active material 4 are assembled so as to obtain a nonaqueous electrolyte battery. Here, the projections and indentations 10 break through an immobile film formed over the surface of the negative active material 5 during its formation, so that an active metallic surface of the material 5 is exposed. As a result, the surface area of the material 5 is increased, the internal resistance of the material 5 is reduced, and the capacity of the discharge current of the battery is increased.
