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.
Claims5
A battery comprising:
- a positive electrode consisting essentially of manganese dioxide as an active material;
- a negative electrode consisting essentially of lithium as an active material, said negative electrode having a much larger electrode potential and a smaller discharge capacity than said positive electrode;
- and
- an electrolyte comprising of an organic material which is a solution of a salt of lithium in an organic solvent.
