nano-silica
Key words:
Thermal insulation materials are divided into three categories: porous materials, heat reflective materials and vacuum materials. The former uses the pores contained in the material itself for heat insulation, because the air or inert gas in the gap has a low thermal conductivity, such as foam materials, fiber materials, etc.; heat reflective materials have a high reflection coefficient and can reflect heat, such as gold, Silver, nickel, aluminum foil or metal-plated polyester, polyimide film, etc. Vacuum insulation material is the use of the internal vacuum of the material to achieve the barrier convection to heat insulation.

Key words:
The product has the characteristics of developed pore structure, strong lipophilic/hydrophilic, low acid replacement amount and good chemical stability, high purity and low metal ion content. When added to PE and other battery separators, it has good dispersion, can improve the pore distribution of the separator and improve the mechanical properties of the composite separator, increase the total amount of colloidal electrolyte, improve the conductivity of the separator, and extend the service life.
