The present invention relates to a high capacity electrochemical cell having a cathode containing an oxide of copper as an active material, as well as an anode, an electrolyte, and separators for use with the cathodes of the invention in an alkaline electrochemical cell.

Separators for alkaline electrochemical cells

Aspects of the present invention provide a high capacity electrochemical cell having an anode, a cathode, and a separator disposed between the anode and cathode. The cathode includes a mixture having a first component, a second component and a third component. The first component includes a first element, the second component includes a second element, and the third component includes the first element and the second element. The mixture can, for instance, be a mixed metal oxide. The separator is configured to provide suitable ionic transport between the anode and the cathode.

Alkaline cells having high capacity

Alkaline battery cells comprising an anode, a cathode, a separator between the anode and the cathode, and an electrolyte are provided with an n-type metal oxide additive that improves electrochemical performance. The n-type metal oxide additive is either a doped metal oxide comprising a metal oxide modified by incorporation of a dopant, or a reduced metal oxide.

Performance enhancing additives for electrochemical cells

An electrochemical cell having a cell can that includes an interior surface, a current collector, a solid cathode contained in the can and in conductive contact therewith, an organic or solid polymer electrolyte comprising lithium salt solutes and aprotic organic solvents has improved storage properties when a coating comprising carbon powder is diposed on the current collector surface and on the adjacent interior surface of the cell can. Further, the cell has advantageous enhanced discharge properties over an expanded temperature range when the cathode additionally comprises a fluoropolymer resin binder.
