A cell of Li-ion battery comprises a plurality of anodes and cathodes of rectangular shape, each one having a current collector tab protruding from a side of the rectangular shape. Each cathode is wrapped in a separator sheet and the cathodes and anodes are stacked on each other. A Li-ion battery comprises a stack of cells and at least four bus bar posts, each bus bar post being positioned in front of one tab in order to create an electrical connection between the tab and the bus bar post. A method for disassembling the battery comprises—holding the anode bus bar posts, and simultaneously pulling the cathode bus bar posts in the direction of the cathode tab protrusions, pulling the anode bus bar posts in the direction of the anode tab protrusions, separating the cathodes from the separators, and separating electrodes from the bus bar posts.

The busbar has a planar portion and multiple blisters that project from it. The blisters have a beam-like structure and provide structural rigidity to the busbar. When the ends of the blisters are connected to the terminals of the cells in the battery, the battery assembly is provided with structural strength. The busbars may be arranged side-by-side or in layers. When in layers, the blisters of the upper busbars project through holes in the lower busbars. Busbar assemblies may include insulating spacers, insulating layers, or venting features. By using the busbar as a structural member, the required strength and weight of the remaining components of the battery pack are reduced.
