What are the characteristics of square lithium batteries?

Features and advantages of prismatic lithium battery The prismatic lithium battery has high packaging reliability; high system energy efficiency; relatively light weight and high energy density; relatively simple structure and relatively convenient expansion. It is currently an important option to increase energy density by increasing the monomer capacity; If the monomer capacity is large, 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, it is difficult to unify the process; the processing automation level is not high, and the monomer difference is large , In large-scale applications, there is a problem that the life of the system is much lower than the life of the monomer. There is more room for the development of soft-packed lithium batteries. The biggest advantage of soft-packed batteries is that they can increase the energy density of power lithium-ion batteries on the existing technical level. According to the statistics of Gaogong Lithium Battery, the soft pack battery is 20% lighter than the aluminum shell battery of the same capacity, and the capacity is 50% higher than the aluminum shell battery of the same size. The subsidy policy for 19 years is still unclear, but it is certain that the amount of subsidy is closely related to the energy density of the battery, and the soft-pack battery has a huge advantage in this regard. According to forecasts, the domestic soft-pack power lithium-ion battery shipments in 2020 are expected to be 35.9MWh, with a penetration rate of 38%, an increase of about 30MWh compared to the 5.5MWh shipment in 2017.
