Our PP (Polypropylene) separator discs are specialized diaphragm components for button lithium-ion batteries, available in three mainstream models: 2320, 2325, and 2500. As a critical safety and performance component in batteries, these discs are engineered with high-purity PP material to provide reliable isolation between positive and negative electrodes while ensuring stable ion conduction. With excellent chemical stability and mechanical strength, they are widely applied in the production of high-quality button lithium-ion batteries for various electronic devices.

• Strong Acid & Alkali Resistance: Made of high-grade PP material, it maintains stable performance in acidic and alkaline environments, avoiding degradation caused by electrolyte corrosion.
• Excellent Chemical Stability: Resists oxidation and chemical reactions with battery components, ensuring long-term reliability and consistent battery performance.
• Reliable Isolation Performance: Precise pore structure effectively separates positive and negative electrodes to prevent short circuits, while enabling smooth ion transmission.
• Strict Quality Assurance: Each batch undergoes rigorous testing for thickness uniformity, pore size distribution, and tensile strength to meet international battery industry standards.
• Customizable Dimensions: Besides standard models (2320/2325/2500), supports customizing diameter and thickness according to specific battery design requirements.
