SHAPED BATTERY CELL AND METHOD OF MANUFACTURE

A method for forming a shaped battery can include: adding electrolyte to a dry battery cell, shaping the battery cell, relieving stress and/or strain from the battery cell, curing the electrolyte, and/or injection moulding a thermoplastic or thermoset around the battery cell. A battery cell can include a cathode, an anode, a separator disposed between the cathode and the anode, a gel polymer electrolyte, an overmoulded housing surrounding the cathode, the anode, the separator, and the gel polymer electrolyte, where the battery cell comprises a non-zero radius of curvature about at least 1 axis.
