ABSTRACT:
A silver oxide primary cell of flat type comprising a casing composed of a cup and a cap electrically insulated from and received in the cup to define a sealed chamber between the cup and the cap. Within the sealed chamber is placed a stack of negative electrode, electrolyte absorbent layer, separator and positive electrode, with the negative and positive electrode held in contact with the cap and the cup, respectively. In order to avoid any possible sharp contact of the positive electrode with the separator, which may otherwise result in internal stresses set up in the separator, the positive electrode has at least one peripheral edge chamfered.
