Abstract
A compact, robust, multifunctional and highly manufacturable rechargeable cylindrical electrochemical cell is provided. In some embodiments, a cell can include a spirally wound assembly having an anode sheet and a cathode sheet separated by separator membranes, each sheet having a electroactive layer on a current collector. At least one of the current collectors can be in electrical communication with conducting tabs that extend from at least one of the anode sheet and the cathode sheet, the conducting tabs extends from an end face of the spirally wound assembly. The centers of the plurality of conducting tabs can be located within a 90 degree quadrant of an end face of the spirally wound assembly.
