NOVELTY - The electrical energy storage device (100) has electrically connected coiled windings (44) sealed from one another in a pressure vessel (104) to prevent flow of electrolyte material between the windings while permitting flow of vapor in the pressure vessel between the windings.    USE - For providing power to an electric vehicle.    ADVANTAGE - Includes windings that have uniform compression to provide uniform resistance in electrochemical circuit formed inside windings. Ensures multiple contacts for each plate in each winding to allow better utilization of capacity of plates, extremely low internal resistance, better discharge capability, and less voltage drop during discharge. Ensures simplified structure since pointed ridges are used to allow current collectors to be pressed into contact with windings without need for welding. Has simplified structure that maintains electrolyte material within winding. Does not need complicated structures e.g. welded tabs, end plates, combination of seal components, to confine electrolyte and gases and to make electrical contact with proper electrode in winding. Uses O ring between casing and current collector to prevent shorting and to seal electrolyte within casing. Provides increased capacity as measured in amp-hours for a specific volume.    DETAILED DESCRIPTION - Each winding disposed in the pressure vessel has a cathode plate, an anode plate, and a separator in between both plates. Each winding defines circular and axially spaced sides. The electrolyte material is located within each winding. Current collectors (68) are secured within the pressure vessel. Each current collector is electrically connected to a pair of windings.    DESCRIPTION OF DRAWING(S) - The figure is a sectional view showing a portion of the electrical energy storage device with several windings held within a casing within the pressure vessel.
