Abstract

A positive electrode composition is presented. The composition includes granules that comprise an electroactive metal, an alkali metal halide, and a metal sulfide composition that is substantially-free of oxygen. A molar ratio of the electroactive metal to an amount of sulfur in the metal sulfide composition is between about 1.5:1 and about 50:1. The positive electrode composition is substantially free of iron oxide, iron sulfate, cobalt oxide and cobalt sulfate. An energy storage device and a related energy storage system are also described.
