Claims19
A cathodic structure for a flexible electrochemical cell comprising a compressed mixture of a powdered cathode active material, chopped graphite fibers, and a binder;
- said mixture being affixed to a flexible metallic current collector;
- a metal tab affixed to said collector;
- and said compressed mixture and said current collector being sealed within a plastic pouch with said metallic tab extending therethrough;
- the plastic of said plastic pouch having sufficient porosity to permit ionic flow therethrough, and the pores thereof being sufficiently small that solid particles will not pass therethrough.
