Product Description

Technical application advantages of high-purity alumina in lithium battery separator coating.
Advantage 1: When the current is too large, it can block the current. The lithium battery diaphragm of PP/PE material is a through hole. When the current is too large, it is easy to cause perforation, which will cause the lithium battery to burn or explode. Use high-purity alumina as the coating material and bonding When the current is too high, the material heats up, and then the high-purity nano-plate-like crystal structure is coated on the surface of the PP/PE material can play a role in adjusting the hole. Because the aluminum oxide coating material will expand in volume, which will close the current conducting holes on the lithium battery diaphragm, thereby blocking the current. When the temperature drops, the volume of the material will shrink, and then the current conducting holes on the diaphragm will be reopened, and the special physical and chemical properties of the material can greatly improve the safety performance of the lithium battery, thereby making it possible for high-power lithium batteries to charge and discharge safely and reliably.

Advantage 2: High-purity nano-alumina  also has very good thermal conductivity. If the battery temperature is too high, this material can conduct heat well, thus solving the problem of poor thermal conductivity of PP/PE materials.

Advantage 3: High-purity nano alumina  material also has excellent flame retardancy. This is because the high-purity alumina material itself is a very good flame retardant, even if the temperature is too high, it reaches the critical point of combustion , The good flame retardant properties of the material will prevent large-scale combustion or even explosion.
