Abstract

In a lithium battery having a negative electrode formed with lithium as active material and the positive electrode formed with manganese dioxide, carbon fluoride or the like as the active material, the discharge capacity of the negative electrode is made smaller than the discharge capacity of the positive electrode, whereby a drop in the battery voltage during the final discharge stage is steepened, and prevents a device using such a lithium battery as a power supply from operating in an unstable manner, thereby improving the reliability of such device.
