Battery Raw Material: Zero-Weld Metal Box for Lithium/Lead-Acid Battery Packs
As a core battery raw material, our Zero-Weld Metal Box for Battery Pack is engineered to solve pain points of traditional welded battery cases—such as poor sealing, weak structural durability, and short service life. It adopts an integrated stretch molding process to achieve a seamless 0-weld structure, making it ideal for lithium-ion, LiFePO4, and other battery pack applications in electric vehicles, energy storage systems, portable electronics, and outdoor equipment.
