With the rapid development of the new energy industry, the application of lithium-ion batteries in power batteries, energy storage systems, and consumer electronics is constantly expanding. Battery safety, cycle life, and energy density have become core indicators of concern for downstream customers. Against this backdrop, alumina powder specifically designed for lithium battery separators, as a crucial component of separator coating materials, is playing an irreplaceable role.
Compared to ordinary alumina materials, alumina powder specifically designed for lithium battery separators has much stricter requirements in terms of particle size distribution, specific surface area, purity, and impurity control. This type of alumina powder not only needs to possess excellent dispersibility but also must ensure the formation of a uniform and dense ceramic layer during the coating process, thereby effectively reducing the thermal shrinkage rate of the separator and improving the overall safety level of the battery.
Key Advantages of Alumina Powder for Lithium-ion Battery Separators
Alumina powder specifically designed for lithium-ion battery separator coating typically offers the following significant advantages:
High-purity alumina: Effectively reduces the potential impact of metallic impurities on battery performance.
Controllable particle size and concentrated distribution: Facilitates the formation of a uniform coating, improving separator consistency.
Excellent high-temperature resistance: Maintains structural stability at high temperatures, reducing the risk of thermal runaway.
Good dispersibility and coating adaptability: Suitable for water-based or solvent-based coating systems, improving production efficiency.
Application Scenarios Continue to Expand
As power batteries develop towards higher energy density and higher safety, ceramic coating of separators has become the mainstream solution in the industry. Alumina powder specifically for lithium battery separators is widely used in:
Power lithium-ion battery separators
Energy storage battery separators
High-safety consumer lithium battery separators
