What are the materials of the lithium battery shell?

What is the material of the lithium battery casing? What is the material of the lithium battery casing? The function of the subcontinent battery casing is to protect the internal materials of the lithium battery from damage. Different lithium battery casing materials have different uses, so what is the lithium battery casing material What? The technicians of Asialandtravel will explain to you: What is the material of the lithium battery shell? 1. Aluminum shell Aluminum shell is a battery shell made of aluminum alloy material, which is mainly used for square lithium batteries. The lithium battery uses aluminum shell The packaging, because of its light weight, is safer than the steel shell. The aluminum alloy shell material structure has significant safety performance, which can be expressed by material thickness and bulging coefficient. Lithium batteries of the same capacity are lighter than steel because aluminum can be made thinner. 2. Steel shell In the early days, most square lithium batteries were made of steel shell, which was mainly used for mobile phone batteries. Later, due to the light weight, low energy consumption, and poor safety of the steel shell, it was gradually replaced by aluminum shells and soft-packaged lithium batteries. However, in terms of the types of lithium batteries and different pictures, most suppliers are using battery steel shell materials. Because of the physical stability of steel materials, the stress is much higher than that of aluminum shell materials. After the optimized design of the processing structure, the safety device is Placed in the battery core, the safety of the steel column battery has reached a new level. At present, most laptop batteries are batteries with steel shells as the carrier. What is the material of the lithium battery casing?
