【Which is Better: Prismatic Batteries or Pouch Batteries?】Prismatic batteries and pouch batteries, as the two main forms of power batteries for new energy vehicles, each have their unique characteristics and advantages. Prismatic batteries, with their shells typically made of aluminum or steel, form a rigid structure. They have rapidly risen in the market due to their high packaging reliability, high system energy efficiency, relatively light weight, and higher energy density. Pouch batteries, on the other hand, can be customized in shape according to customer needs, offering greater design flexibility. They also typically have lower internal resistance, reducing self-discharge. However, due to the complexity of their production process, the production cost of pouch batteries is relatively higher.
