A brief introduction to square lithium batteries.

Square lithium batteries usually refer to aluminum or steel shell square batteries. The popularity of square lithium batteries in China is very high. With the rise of automotive power batteries in recent years, the contradiction between car range and battery capacity has become increasingly prominent. Domestic power lithium battery manufacturers often use square aluminum shell lithium batteries with higher energy density because the structure of square lithium batteries is relatively simple, unlike cylindrical lithium batteries which use high-strength stainless steel as the shell and have explosion-proof safety valves and other accessories. Therefore, the overall weight of the accessories is lighter and the relative energy density is higher. The square lithium battery adopts two different processes: winding and stacking.

However, due to the fact that square lithium batteries can be customized according to the size of the product, there are thousands of models on the market, and due to the large number of models, it is difficult to unify the process. There is no problem using square batteries in ordinary electronic products, but for industrial equipment products that require multiple series and parallel connections, it is better to use standardized cylindrical lithium batteries, which ensures the production process and makes it easier to find replaceable batteries in the future.

Generally speaking, square lithium batteries and soft pack lithium batteries each have their own advantages and disadvantages. Each battery has its own areas of advantage. For example, there are more lithium iron phosphate batteries in square lithium batteries, while there are more ternary batteries in soft pack lithium batteries. With the introduction of new subsidies for new energy vehicles, the system energy density of batteries has become an important assessment indicator.
