Thermal Material High Purity Alumina used as Lithium Battery Separator Coating also has very good thermal conductivity. When the battery temperature is too high, this material can conduct heat well, thereby solving the problem of poor thermal conductivity of PP / PE materials.
The role of high-purity alumina in lithium battery separator coating：
1. When the current is too large, it can block the current. The lithium battery separator of PP / PE material is a through-hole. When the current is too large, it is easy to cause perforation, which may cause the lithium battery to burn or explode. Thermal Material High Purity Alumina used as Lithium Battery Separator Coating is used as a coating material together with a binder On the surface of PP / PE material, it can play the role of pore adjustment
2. Thermal Material High Purity Alumina used as Lithium Battery Separator Coating also has very good thermal conductivity. When the battery temperature is too high, this material can conduct heat well, thereby solving the problem of poor thermal conductivity of PP / PE materials.
3. Thermal Material High Purity Alumina used as Lithium Battery Separator Coating also has excellent flame retardancy, even if the temperature is too high to reach the zero-combustion point, the material's good flame-retardant properties will prevent a large-scale combustion or even explosion.
