Abstract
An electrochemical cell comprising a medium rate electrode region intended to be discharged under a substantially constant drain and a high rate electrode region intended to be pulse discharged, is described. Both electrode regions share a common anode and are activated with the same electrolyte.
Claims24
An electrochemical cell, comprising:
- a) a casing;
- b) an anode provided in a folded, accordion pleated shape and comprising an anode active material;
- c) a first cathode of a first cathode active material and having at least a first side;
- d) a second cathode of a second cathode active material and having at least a second side;
- and
- e) an electrolyte activating and operatively associating the anode with the first cathode and the second cathode, and wherein the first cathode and the second cathode are disposed between the folds of the anode with portions of the anode in a face-to-face relationship with at least the first and the second sides of the respective first and second cathodes to provide a first portion of the anode associated with the first cathode and a second portion of the anode associated with the second cathode being dischargeable independent of each other to provide separate and independent sources of electrical energy.
