Abstract:
1. An electrochemical cell comprising: a) an anode; b) a cathode comprised of a first current collector, a first cathode active material mixture having a first energy density and a first rate capability, and a second cathode active material mixture having a second energy density and a second rate capability, wherein the first cathode active material mixture comprises silver vanadium oxide (SVO) mixed with about 3%, by weight, of a conductive diluent and about 3%, by weight, of a first binder and the second cathode active material mixture comprises CF c) wherein the first rate capability of the first cathode active material mixture is greater than the second rate capability of the second cathode active material mixture, and d) wherein the second energy density of the second cathode active material mixture is less than or equal to, but not greater than, the first energy density of the first cathode active material mixture; e) a separator positioned between the anode and the cathode to prevent direct physical contact between them by allowing for electrochemical reactions to take place; and f) an electrolyte activating the anode and the cathode.
