ELECTROCHEMICAL BATTERY AND ITS PARTS

PROBLEM TO BE SOLVED: To provide an electrochemical battery, having an enlarged portion for containing an electrochemically reactive anode material. SOLUTION: This electrochemical battery 10 is typically a button type air- depolarized battery has non-reactive elements considerably thinner than those of a battery of the prior art. Such elements are thinned due to the improved structure. In these elements, there is an anode can 24 manufactured from a metal strip structure many parts of which are made of steel. Another element is a cathode can 40, which has its temper adjusted, improved rigidity and sufficient ductility for allowing shaping of the cathode can. The thickness of the non-reactive elements of the battery 10, and therefore, the volume occupied by the non-reactive elements are reduced, which increases the volume of a portion for holding the electrochemically reactive anode material 26, so that the capacity of the battery is increased.
