What is a square lithium battery?deep cell marine battery direct sales

　　Lithium -ion batteries are divided into square lithium batteries, column -shaped lithium batteries and buckle lithium batteries according to the shape; lithium batteries are divided into aluminum shell lithium batteries, steel shell lithium batteries, and soft bag batteries according to outsourcing materials; Lithium iron phosphate, lithium manganate, lithium polymer. What are the square lithium batteries? What is his structure like? What are the advantages and disadvantages?

　　Square lithium batteries usually refer to aluminum shells or steel shell square batteries. The penetration rate of square batteries is very high in China, because the structure of square batteries is moreSimply, unlike the cylindrical battery, stainless steel is used as a shell and an attachment with explosion -proof safety valves. Therefore, the overall attachment weight must be light and relatively high energy density. The square battery has two different processes: scroll and stacker.

　　advantage

　　High -reliability of square lithium batteries; high system energy efficiency; relatively light weight, high energy density; simple structure and relatively convenient expansion, which is currently an important option to increase energy density by improving the capacity of the single; The system composition is relatively simple, making it possible to monitor the monomer one by one; another benefit brought by the system is that the stability is relatively good.

　　shortcoming

　　The disadvantage is that because the square lithium battery can be customized according to the size of the product, there are tens of thousands of models on the market, but because there are too many models, the process is difficult to uniform; Large, in large -scale applications, there is a problem that the system life span is much lower than the single life.

　　A typical square lithium battery, the main components include: top cover, shell, positive plates, negative plates, and blocks of stacks or wounds, insulation parts, safety components, etc. Among them, the two in the red circle are the security structure, NSD acupuncture safety device; OSD over charge protection device.
