Abstract:
1. An electrochemical storage cell comprising: a protective, prismatic-shaped shell having a first electrical terminal at one end thereof and a second electrical terminal at the other end thereof; a core that fits snugly within the shell, the core comprising an anode sheet comprising active materials formed on a substrate and a metal foil current collector extending from a longitudinal edge of the anode sheet and connected to the first electrical terminal; a cathode sheet comprising active materials formed on a substrate and a metal foil current collector extending from a longitudinal edge of the cathode sheet and connected to the second electrical terminal; a separator sheet between the cathode sheet and the anode sheet; wherein the anode sheet, cathode sheet, and separator sheet are wound to form a flattened coil structure having opposed flattened sides and opposed arcuate sides, and wherein the anode sheet terminates at an arcuate side and the cathode sheet terminates at an arcuate side.
