Abstract: Generally described, one or more aspects of the present disclosure relate to systems, methods, and devices for trimming and peeling electrode films. The system can be integrated into a calender rolling system and can create multi-lane films with clean edge quality for lamination. The system can include a trimming device including a cutting device, and a material removing device positioned downstream from the cutting device, the material removing device including a scraper element, a support element positioned upstream from the scraper element, and a vacuum element.

Abstract: 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.
