Abstract
An electrochemical cell comprising an anode, a cathode comprised of a first current collector, a first cathode active material having a first energy density and a first rate capability, and a second cathode active material having a second energy density and a second rate capability, and an electrolyte activating the anode and the cathode. The first rate capability of the first cathode active material is greater than the second rate capability of the second cathode active material, and the first energy density of the first cathode active material is greater than or equal to the second energy density of the second cathode active material as a result of the addition of one or more diluents to the second cathode active material. A preferred configuration for the cathode is SVO/current collector/CFx with the SVO facing a lithium anode.
