Product Detail

Electronic Grade Nano SiO₂ Solution CAS 7631-86-9 for Lithium Battery Separator Coating

Product Overview

Electronic Grade Nano SiO₂ Solution (CAS 7631-86-9) is low-impurity water-based colloidal silica with uniformly dispersed nano silicon dioxide particles. It serves as key inorganic raw material for lithium battery separator ceramic coating. After coating formation, it effectively improves thermal dimensional stability, puncture resistance and flame retardancy of separators, restraining thermal runaway risks and greatly lifting the safety performance of lithium ion batteries. The product features good compatibility with water-based binders and stable coating slurry system.

Core Features

Low Metal Impurity: Strictly controlled ionic impurities, reduce self-discharge and avoid adverse effects on battery electrochemical performance.
Uniform Nano Particle Size: Less agglomeration, form compact and even ceramic coating layer.
Excellent Dispersion Stability: Long-term storage without precipitation, convenient for slurry preparation and continuous coating production.
Outstanding Heat Resistance: Significantly raise thermal deformation temperature of separators.
Good Coating Adaptability: Compatible with aqueous PVDF, acrylic and other common binders.
Improve Safety Performance: Enhance puncture resistance, inhibit internal short circuit and promote battery cycle stability.
