1. An electrochemical cell stack comprising:
- (a) a segmented cathode material comprising four sections in the form of a rectangle, said four sections being connected together at their inner adjacent corners with a flexible current collector material;
(b) a strip of anode material including a current collector having flexibility sufficient to permit the strip to be folded over onto itself; and
(c) non-conductive porous separator means comprising an electrolyte positioned between said cathode material and anode strip to prevent electrical contact between said cathode material and anode strip, said anode strip and cathode material being folded over onto each other at right angles to each other to provide a cell stack.

Abstract
A high density cell stack is provided utilizing a flexible cathode material having at least four sections in the form of a rectangle and flexible anode materials folded over each other at right angles. A suitable anode material is lithium and a suitable cathode material is manganese dioxide. The disclosed cell stacks are rapidly manufactured to provide high density cells with good mechanical stability and good stability against shorting.
