What are the advantages and disadvantages of square lithium batteries?

 

Advantages: high reliability of prismatic lithium battery packaging; high system energy efficiency; relatively light weight and high energy density; simpler structure and relatively convenient expansion. It is currently an important option for increasing energy density by increasing monomer capacity; monomer capacity Larger, 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 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 monomer difference is relatively high. Large, in large-scale applications, there is a problem that the life of the system is much lower than the life of the monomer.
