Products Description
Zinc-ion battery separator film:
PP membrane, non-woven fabric sulfonation treatment:
1) Hydrophilic treatment increases the ability of the separator to absorb electrolyte.
2) After sulfonation treatment, the battery has a high charge retention rate, lower internal resistance, and is conducive to high current discharge.
3) Increases the energy efficiency of the battery under high current density conditions.
4) Used in zinc-ion batteries to induce zinc deposition and prevent dendritic growth.

PP film, non-woven fabric sulfonation treatment effects:
1. Hydrophilic treatment increases the separator’s electrolyte absorption capacity.
2. After sulfonation treatment, the battery maintains a high charge retention rate, low internal resistance, and is beneficial for high current discharge.
3. It increases the energy efficiency of the battery under high current density conditions.
4. Application in zinc-ion batteries can induce zinc deposition without dendrite growth.
