Product Overview
This product is high-purity fused silica micro powder, specifically designed for lithium battery separator coatings. It significantly enhances the separator's high-temperature resistance, mechanical strength, and electrolyte wettability. Its ultra-fine particle size distribution (D50 0.5μm-50μm) and spherical structure contribute to the formation of a uniform and dense coating, optimizing battery safety and cycle life.

Key Parameters

  • Purity: ≥99%

  • Particle Size Range (D50): 0.5μm-50μm (customizable)

  • Morphology: Spherical or near-spherical, smooth surface

  • Density: 2.2 g/cm³

  • Melting Point: ~1700°C

  • Dielectric Constant: Low (ideal for high insulation requirements)

  • Moisture Content: <0.1%

Core Advantages

  • High Purity & Stability: ≥99% purity with extremely low impurity levels, preventing side reactions in batteries.

  • Controlled Particle Size: Precise grading technology meets various separator coating processes (e.g., wet/dry coating).

  • Exceptional Thermal Stability: Outstanding high-temperature resistance, suppressing separator thermal shrinkage.

  • Enhanced Performance: Improves separator porosity uniformity and promotes lithium-ion transport efficiency.

Applications

  • Lithium-ion battery separator coatings (power batteries, energy storage batteries, 3C digital batteries)

  • Ceramic separator modification materials

  • High-temperature insulation materials

Packaging & Storage

  • Packaging: 25kg/bag (moisture-proof bag) or customized upon request.

  • Storage: Keep in a cool, dry place to avoid moisture absorption and caking.
