  • FAQ

  • As a critical insulating barrier inside lead‑acid batteries, PE battery separator physically isolates positive and negative electrodes to avoid internal short‑circuit risk, without obstructing electrolyte ion migration during charge‑discharge cycles.

     

    Formulated with polyethylene and high‑purity silica filler, the material forms densely distributed micro‑pores. It stands up to long‑term corrosive sulfuric‑acid environment inside batteries and resists oxidation under continuous working conditions. Great physical toughness reduces damage risk caused by plate expansion and active‑material shedding.

     

    Beyond standard flat roll materials, we support finished‑form supply: separator sleeves and pre‑made envelope pockets for automated battery assembly lines. The PE+GM blended grade optimizes liquid‑holding capacity for deep‑cycle and energy‑storage working scenarios.

     

    Suitable for automotive starting batteries, traction power batteries and stationary energy‑storage batteries. Custom sizes and thickness options are available to match customers’ production specifications.
