![]() There are up to 500 types of square aluminum battery with different sizes, which are widely used in exploring and mapping, medical equipment, portable testing equipment, interphone, acoustic enclosure, mobile DVD, digital camera and so on. Products comply with GB, UN and ROHS instructions. It can be designed and customized according to customer needs.Įnvironmental friendly: It has passed ISO14000 environmental system certification. ![]() It has low internal resistance, high discharge rate and stable discharge platform. Good cycling performance: It has low attenuation, and it can maintain more than 80% of the initial capacity after 500 cycles.Īdopt square aluminum shell structure, and the combination cover plate with explosion-proof valve, which has high safety performance and no leakage High energy density: volume to energy density is 550Wh/L Therefore, in large-scale applications, the system life is far lower than the single battery life. However, because square lithium batteries can be customized according to the size of the product, there are too many models on the market, which makes it difficult to unify the process, the production automation level is not high, and the single battery is quite different. Its structure is relatively simple, the single battery capacity is large, and the system composition is relatively simple. Square lithium battery encapsulation has good reliability, nice system energy efficiency, light weight and high energy density. ![]() Square lithium battery usually refers to aluminum or steel shell square lithium battery. Lithium ion batteries are divided into square lithium batteries, cylindrical lithium batteries (such as 18650, 18500, etc.) and pouch polymer lithium batteries. 1) What is prismatic lithium ion battery? 1.Overview of square lithium battery
