Square batteries are more flexible and can be customized according to the specific needs of the products they carry. Hence the difference in size. Regardless of manufacturing process or application standards, there is no clear standard division like cylindrical batteries.
At the same time, due to its structural characteristics and standardization, the level of automation in cylindrical battery production is higher. The advantage of cylindrical batteries is that their energy density per unit is higher than that of square hard-shell batteries.
Mainstream battery suppliers in China, represented by CATL, also use square hard-shell batteries as their main R&D products. This is also one of its advantages: there are enough suppliers. For car companies, this also means that the purchase cost of batteries can be effectively reduced.
The pouch battery itself is lighter. With the same capacity, its weight is 20% lighter, and its capacity is 50% higher than that of square batteries. Therefore, the theoretical energy density of soft batteries is higher than that of square and cylindrical batteries.
Therefore, the theoretical energy density of soft batteries is higher than that of square and cylindrical batteries. Soft batteries adopt a lamination type and pursue a slimmer size, making them the lightest in weight at the same capacity and density.
The chemical activity of square batteries is poor at the corners. Battery performance declines more obviously after long-term use. In short, whether cylindrical, square, or soft lithium batteries are developing rapidly, they have been well used in their respective application fields.
