Cell of An Energy Storage Device

The present invention discloses an energy storage device cell that features an electrode assembly on a central shaft. This entire assembly is enclosed within a casing that includes a cover and a bottom, which function as the two opposite external terminals. The electrode assembly consists of two electrode plates, each with tabs, separated by interposed separators. The shaft runs through the electrode assembly, protruding from both the cover and the bottom, establishing a channel of convective flowpathway. Disclosed herein is the shaft in combination with the welded ties that connect the two opposite sets of electrode tabs, integrating electrical and thermal conductivities simultaneously into the cell structure.
