[0002] The rapid development of electronic devices, particularly electric vehicles, has led to a growing demand for high-capacity, high-energy-density batteries. Prismatic aluminum-cased batteries, with their high energy density and fast charging speeds, are becoming a mainstream option in the electric vehicle market. The development of prismatic aluminum-cased batteries dates back to the early 1990s, with their invention by Sanyo Electric in 1995. With continuous technological advancements, the application areas of prismatic aluminum-cased batteries are expanding, encompassing energy storage, smart grids, and other fields.
