Benefits of technology

[0018]According to the present disclosure, the influence of heat generated at a welding spot between an electrode tab and an electrode lead on the performance of a secondary battery may be minimized. Accordingly, in the design of a large capacity secondary battery, the battery performance may be close to an ideal condition.

Problems solved by technology

Also, as the output and charging capacity required for an energy storage system becomes higher, the size of secondary batteries also increases.
