Abstract
Primary cell, in which the positive active material is silver chromate and in which the electrolyte may be constituted by a lithium perchlorate solution in propylene carbonate. According to the invention silver powder is added to the silver chromate in a proportion comprised between 5% and 30% by weight. A primary cell thus obtained may be used in an environment having a high temperature, such as an electrical device whose components heat up without any possibility of cooling.
