International Classification:

H01M 452
H01M 616

US Classification:

429194

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.

Filed:

Sep 30, 1982

Appl. No.:

6/431881

Inventors:

Luverne H. Barnette - Derry NH
Charles C. Liang - Clarence NY

Assignee:

Duracell Inc. - Bethel CT

International Classification:

H01M 618

US Classification:

429191

Abstract:

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.
