What are the basic structure and advantages and disadvantages of square batteries

A typical prismatic lithium-ion battery, the important components include: top cover, case, positive plate, negative plate, separator laminated or winding, insulating parts, safety components, etc. The shell is generally a steel shell or an aluminum shell. As the market is driven by the pursuit of energy density and the progress of the production process, the aluminum shell has gradually become the mainstream. Advantages: high reliability of prismatic battery packaging; high system energy efficiency; relatively light weight and high energy density; relatively simple structure and relatively convenient expansion. It is currently an important option for increasing energy density by increasing monomer capacity; large monomer capacity , The system configuration is relatively simple, which makes it possible to monitor the monomers one by one; another advantage brought by the simple system is that the stability is relatively good. Disadvantages, because the square lithium-ion battery can be customized according to the size of the product, there are thousands of models on the market, and because there are too many models, the process is difficult to unify; the level of production automation is not high, and the monomers are different. Larger, in large-scale applications, there is a problem that the life of the system is much lower than the life of the monomer.
