Mixed heavy metal polysulfides which are insoluble in non-aqueous electrolytes and having the formula

Insoluble mixed heavy metal polysulfide cathodes

A solid state cell having a solid cathode, a solid electrolyte, and a solid anolyte comprised of at least 50% by volume of ionically conductive materials such as the electrolyte and 50% or less by volume of an active metal. The anolyte is either the cell anode or alternatively the anolyte is an additional structural member within said cell positioned between an anode, comprised of the same active metal, and the solid electrolyte.

Solid state cell with anolyte

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.

A solid state cell having a solid cathode, a solid electrolyte, and a solid anolyte comprised of at least 50% by volume of ionicially conductive materials such as the electrolyte and 50% or less by volume of an active metal. The anolyte is either the cell anode or alternatively the anolyte is an additional structural member within said cell positioned between an anode, comprised of the same active metal, and the solid electrolyte.

A solid state electrochemical cell containing a cathode comprising a compound which is solid at ambient temperatures and which contains a halogen atom, a chalcogen atom and an atom of a third element, with the chalcogen and halogen not in a redical grouping.
