What are the components and features of Rechargeable Square Pouch Battery?

Rechargeable Square Pouch Battery generally refers to aluminum shell or steel shell Rechargeable Square Pouch Battery. The popularity of Rechargeable Square Pouch Battery is gradually increasing. With the rise of automotive power batteries in recent years, the contradiction between car mileage and battery capacity has become increasingly prominent. Power battery manufacturers generally use aluminum shell Rechargeable Square Pouch Battery with higher battery energy density. This is because the structure of Rechargeable Square Pouch Battery is relatively simple, unlike Rechargeable Cylindrical Pouch Battery, which uses higher-strength stainless steel as the shell. Explosion-proof safety valve and other accessories, so the overall accessory weight is lighter, and the relative energy density is higher. At present, the square battery has two different processes: winding and lamination.


A typical Rechargeable Square Pouch Battery, its main components include: top cover, case, positive plate, negative plate, separator laminated or winding, insulation and safety components, etc., of which, the two in the red circle One is a safety structure, NSD acupuncture safety device; OSD overcharge protection device.

The characteristics of Rechargeable Square Pouch Battery, this kind of battery package has high reliability, so the system energy efficiency is also high, thanks to the compact structure of Rechargeable Square Pouch Battery, the relative weight will be lighter, resulting in higher energy density; Simple and relatively convenient for expansion, it is currently an important option for increasing the energy density by increasing the capacity of the monomer; the larger the monomer capacity, the relatively simple system configuration makes it possible to monitor the monomers one by one; another advantage brought by the simple system The stability is relatively good.
