ABSTRACT:
A high pulse power electrochemical cell comprising an alkali metal-aluminum alloy anode, a nickel anode current collector, a calendared mixed metal oxide cathode active material pressed onto a cathode current collector comprising aluminum and a nonaqueous electrolytic solution, is described. The electrolytic solution preferably comprises at least one ion-forming alkali metal salt of hexafluorophosphate with the alkali metal salt being similar to the alkali metal comprising the anode. Lithium is the preferred alkali metal. This cell system produces high current pulses and can be housed in a casing having a reduced volume with respect to conventional electrochemical systems. Additionally, the anode/electrolytic solution exhibits reduced voltage delay without comprising heat dissipation.
