BATTERY HAVING INTERNAL ELECTROLYTE FLOW PATH AND/OR INTEGRAL HEAT SINK
First Claim
1. A battery, comprising:
- at least one cathode sheet formed from a metallic foil electrode coated with an active material;
at least one anode sheet formed from a metallic foil electrode coated with an active material, the anode sheet being disposed in overlying relationship with the cathode sheet so at provide at least one cathode/anode electrode pair;
a separator between the cathode and anode sheets;
electrolyte;
a packaging encasing the at least one cathode and anode sheets and containing the electrolyte;
characterized in that at least the cathode active material is formed with ridges and depressions therein for enabling the electrolyte to flow and wet the electrode.

Abstract
In one aspect, a battery is provided having at least one cathode sheet formed from a metallic foil electrode coated with an active material and at least one anode sheet formed from a metallic foil electrode coated with an active material. The anode sheet is disposed in overlying relationship with the cathode sheet so as to provide at least one cathode/anode electrode pair. The battery further includes a separator between the cathode and anode sheets, electrolyte, and a packaging encasing the at least one cathode and anode sheets and containing the electrolyte. The active material on the cathode sheet(s) is formed to have ridges and depressions therein enabling the electrolyte to flow and wet the electrode(s).

8. A prismatic battery, comprising:
-
a first stack of cathode/anode pairs; a second stack of cathode/anode pairs; wherein each cathode/anode pair comprises a flexible cathode sheet, a flexible anode sheet overlapping and co-extensive with the cathode sheet, and a separator interleaved between the cathode sheet and anode sheet; a heat conducting plate having first and second faces, wherein the first stack abuts the first plate face and the second stack abuts the second plate face, the plate extending past a periphery of the first and second stacks to provide a heat dissipation surface; a casing housing the first and second stacks and in thermal contact with the plate. - View Dependent Claims (9, 10, 11, 12, 13)
