High-Performance PE Battery Separator for Superior Energy Storage
Ultra-thin 0.25mm design ensures minimal internal resistance, enhancing battery efficiency and lifespan. Precision-engineered 128*120mm dimensions for seamless fit in high-capacity lithium-ion/polymer battery assemblies. Reinforced 1.0mm edge strength prevents tearing under extreme mechanical stress, ideal for EV batteries, power tools, and industrial energy systems. Medical-grade polyethylene material guarantees chemical inertness, resisting electrolyte corrosion for stable performance in -40°C to 120°C environments. Microporous structure (0.1-1μm pores) optimizes ion flow while blocking dendrite growth—critical for fast-charging consumer electronics and renewable energy storage. Roll-to-roll laser calibration ensures ±0.02mm thickness consistency, meeting UL/IEC safety standards for OEM mass production. Bulk-packaged for wholesale buyers: 10,000+ units per pallet with certified moisture-proof barrier packaging. Custom die-cutting available for volume orders.
