Material: 304 Stainless Steel (Imported Raw Materials)
Customization: Supported (OEM/ODM Available)
Origin: China
The 26650 Cylindrical Battery Steel Case Assembly is an all-in-one solution for high-performance lithium batteries, integrating a precision-engineered steel case, explosion-proof cap, PTC (Positive Temperature Coefficient) component, and upper/lower insulation sheets. Crafted to 26650 standard dimensions, the assembly ensures perfect compatibility with automated production lines. The explosion-proof cap releases excess pressure to prevent hazards, while the PTC provides thermal protection by limiting current during overheating. The insulation sheets eliminate short-circuit risks, and the high-strength steel case offers structural durability and efficient heat dissipation. Ideal for energy storage systems, electric tools, and portable power devices, this assembly delivers reliable safety, stable performance, and streamlined battery manufacturing.
