Abstract

A flexible battery 1 comprises a stack of electrochemical cells 2, each cell being movable relative to an adjacent cell when the battery is bent. An insulating layer is preferably provided between each cell, and may comprise a pouch in which the anode, cathode, anode and cathode current collectors and separator are located, the pouch forming the insulating layer. In a further aspect, an electrochemical cell suitable for a flexible battery, comprises an anode, anode current collector, cathode, cathode current collector and separator, all located within a pouch, wherein anode and cathode cell lead-outs extend from the pouch and are attached to an external surface of the pouch to form respective anode and cathode battery lead-out pockets. Also disclosed is a cell module including this cell, a method of forming the flexible battery, a method of forming the electrochemical cell for a flexible battery and a method of forming the cell module.
