What material is used for the lead-acid battery shell?

Now new energy vehicles use batteries, and the battery casing plays a protective role. Today the author and you all come to know about lead-acid batteries. The most obvious feature of a lead-acid battery is that it has a removable plastic sealing hole on the top. So what material is used for the lead-acid battery shell? What is the material of the lead-acid battery shell? It is known that the general lead-acid battery shell generally uses ABS, PP, PE and other materials, while the high-end valve-controlled sealed battery generally uses ABS. Valve-controlled batteries generally use PP and PE materials. The outer shell of lead-acid battery is mainly used to hold the electrolyte and the plate assembly. The outer shell should have the properties of acid resistance, heat resistance, shock resistance, etc., before using hard rubber. At present, domestic processing of polyacrylic acid plastic shells has begun. This kind of shell not only has the characteristics of acid resistance, heat resistance, shock resistance, high strength, etc., but also has a thin shell wall (usually 3.5mm, while the hard rubber shell has a wall thickness of 10mm), light weight, beautiful appearance, and transparency. The outer shell of the lead-acid battery should be made of materials with acid resistance, heat resistance, shock resistance, good insulation, and mechanical strength. In recent years, with the rapid development of engineering plastics, polypropylene plastic shells have been widely used. Compared with the hard rubber shell, it has better toughness, the light and thin wall thickness is only 3.5 mm, and the rubber shell wall thickness is about 10 mm), and the processing technology is simple, the processing efficiency is high, and it is easy to heat seal without any harm. Impurities, beautiful appearance, transparency, such low advantages. Now you know what material the lead-acid battery shell is used for! With the development of new energy technology, the battery shell brand is also developing rapidly, and the technology is becoming more and more mature.
