ABSTRACT:
An electric energy storage device comprises a casing and a coiled winding disposed within the casing. The winding includes a cathode plate, an anode plate, and a separator located between the cathode and anode plates. The cathode and anode plates are wound in an offset relationship. Two current collectors are secured to the casing, one current collector being pressed against the first side of the winding to contact the cathode plate, and the other current collector being pressed against the second side of the winding to contact the anode plate. A pressure vessel is provided to hold at least one of the casings having at least one of the windings therein. An electric vehicle is provided including a plurality of the energy storage devices. An apparatus for manufacturing the winding is provided including a frame, an arbor rotatably mounted on the frame, an arbor rotation mechanism for rotating the arbor to wind the anode plate, the cathode plate and the separator about the arbor to thereby form the winding, the diameter of the winding increasing from an initial diameter to a completed diameter during the winding. A series of rollers are arranged on the frame about the arbor and are movable away from the arbor, only a portion of the series of rollers contacting the winding when the winding is of the initial diameter, and additional rollers contacting the winding when the winding reaches a first intermediate diameter between the initial and completed diameters.
