Disclosed is a current collector and method for increasing the electrical conductivity between the collector, casing, and the winding in the cell. The current collector comprises a sheet of highly conductive metal, such as pure nickel, having a plurality of protruding tabs arranged about its periphery. The tabs are folded upwardly to receive the winding and to fit inside the casing. The tabs are then welded to the casing, using a series welding technique through the outside of the casing.
