Flexible cells and batteries formed therefrom

DETAILED DESCRIPTION What is claimed is: 1.
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.
2.
The cathodic structure of claim 1 wherein said compressed mixture further includes graphite powder.
3.
The cathodic structure of claim 1 wherein said structure has a total thickness less than 40 mils.
4.
The cathodic structure of claim 1 wherein said mixture contains at least 50 percent cathode active material by weight.
5.
The cathodic structure of claim 1 wherein said mixture contains at least 0.
1% graphite fibers by weight.
6.
The cathodic structure of claim 1 wherein said cathode active material is silver chromate (Ag.
sub.
2 CrO.
sub.
4).
7.
The cathodic structure of claim 1 wherein said plastic is a heat sealable, flexible, microporous polymeric material.
8.
The cathodic structure of claim 1 wherein said metallic current collector is an expanded metal with the metals of said current collector and said tab being individually selected from the group consisting of stainless steel, tantalum, titanium, molybdenum, zirconium, niobium, vanadium, chromium, and tungsten.
9.
A flexible, non-gassing, high energy density electrochemical cell comprising a flexible, active metal anode having an electrically conductive tab operatively associated therewith; an organic electrolyte; a cathodic structure as defined in claim 1; and an outer, flexible, electrolyte impermeable container hermetically sealed around said anode, said electrolyte and said cathodic structure, with said tabs extending through said outer container
