What is the best-selling battery case on the market?

What is the best-selling material on the market? What is the best-selling material on the market? It is known that the best-selling material on the market at present should be the aluminum alloy case, which is also a metal type. Today, we tell you the reason for the best-selling aluminum box: aluminum alloy has low density, but high strength, close to or exceeds high-quality steel, good plasticity, possible processes are divided into various images, and has excellent electrical conductivity, thermal conductivity and resistance. Corrosive, widely used in the industry, the number of uses is second only to steel. There is also a stainless steel rigid casing, and there are more battery casings made of this material. Stainless steel is stainless steel, acid-resistant steel, air, steam, water and other weakly corrosive media, or stainless steel is called stainless steel; and steel that is resistant to chemical corrosion media (acid, alkali, salt and other chemical etching) is called acid-resistant steel. Lithium battery shell alloy material structure has significant safety performance, which can be expressed by material thickness and expansion coefficient. Lithium batteries of the same capacity are lighter than steel because aluminum can be made thinner. According to the working mechanism of lithium batteries, lithium ions are not inserted during charging, and the volume of the positive electrode increases. During the discharge process, lithium ions are inserted from the positive electrode and expanded from the negative electrode. It will cause the solid to expand, and the coefficient of expansion can be reduced by proper alloy formulation. What is the best-selling material on the market? From the above, we can know that the best-selling aluminum shell on the market is the aluminum shell, but the steel shell is also relatively popular. If you have a friend who wants a battery case, you can inquire. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
