Abstract
Heavy metal polysulfides which are insoluble in non-aqueous electrolytes and having the formula M.sub.x.sup.m (S.sub.y) .sub.z.sup.-2 (wherein M is a heavy metal such as iron, cobalt, copper or nickel; S is sulfer; mx=2z; and y is greater than two) are utilized as very high energy density cathodes in non-aqueous electrochemical cells.
