Product Desciption
Product Introduction
High Purity Alumina used for lithium battery separator coating is an inorganic substance with high thermal stability and chemical inertness. It is a good choice for battery separator ceramic coating. It has the properties of insulation, heat insulation and high temperature resistance; as the capacity of lithium-ion rechargeable batteries continues to increase, the internal energy accumulation becomes greater and greater, and the internal temperature will increase. It may occur that the temperature is too high and the negative electrode separator will be melted and cause a short circuit. Because high-purity alumina has the characteristics of insulation, heat insulation and high temperature resistance, it can be used in the coating of lithium batteries, which can avoid short circuits between electrodes and improve the safety of lithium batteries.
Product technical parameters and table
The product application
1. Uniformity of particle size, which could be well bonded to the diaphragm without blocking the diaphragm pore size.
2. The alumina has high purity, does not introduce impurities, and does not affect the inner environment of the battery.
3. The crystal structure of alumina is consistent, and the compatibility and infiltration of alumina to electrolyte.
4. Reduce the mechanical micro-short circuit in the circulation process, improve the cycle life.
5. The aluminum oxide coating can neutralize the free HF in the electrolyte and improve the acid resistance of the battery.
6. Alumina coating increases the tortuosity of micro pores, and the self-discharge is lower than that of ordinary diaphragms.
7. The alumina coating has excellent high temperature resistance, and can maintain the shape of the diaphragm above 180 degrees celsius.
