High Purity Alumina for Lithium Battery Separator Coating

When the current is too large, High Purity Alumina for Lithium Battery Separator Coating 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. High Purity Alumina for Lithium Battery Separator Coating is used as a coating material together with a binder. It can play the role of pore adjustment on the surface of PP / PE material, that's because:

High Purity Alumina for Lithium Battery Separator Coating has a plate-like crystal structure. When the current is too large, the material heats up, and the plate-like crystal structure of high-purity nano-alumina coating material will expand in volume, which will close the current conduction on the lithium battery separator hole, thereby blocking the current. The safety performance of the lithium battery can be greatly improved, thereby providing the possibility of high energy safety and safe and reliable charging and discharging of the high-power lithium battery.
