Abstract
The invention relates to a positive active material for primary batteries having high energy density and constituted by a metal salt whose cation is monovalent silver and whose complex anion is composed of a central atom and ligands, for example a ferrocyanide or a ferricyanide. According to the invention, the ligands are at least partly constituted by monovalent anions. Application is to lithium primary batteries of the so-called button type or other conventional constructions useful particularly as energy sources for watches or heart stimulators or pacemakers wherein essential requirements are substantially uniform discharge voltage from inception of use to exhaustion and relatively long life.
