Summary:Energy storage devices and methods of manufacturing thereof, such as a lithium ion battery, without tabs connecting the electrode jellyroll to the can are described. A series of flags may be cut, bent and interleaved over one another to create a connection point for upper and lower collector plates within a can. The upper and lower collector plates may be welded directly to the interleaved flags to create connection points for the anode and the cathode within the energy storage device.
