Abstract

A secondary electrochemical cell comprising a medium rate electrode region in a side-by-side electrode plate configuration intended to be discharged under a substantially constant drain and a high rate electrode region disposed in a jellyroll wound configuration intended to be pulse discharged, is described. Both electrode regions share a common anode and are activated with the same electrolyte.
