Product Introduction:
HPA for lithium battery separator coating, alpha phase, has stable crystalline phase, good consistency of crystalline shape and appearance, rounded grains, good suspension stability and good dispersion. It has high purity up to 99.99%, 99.999%, uniform particle size distribution and D50 can be adjusted and controlled according to customer requirements. HPA for lithium battery separator coating has good electrical properties, high insulation resistance and insulation breaking voltage, low dielectric constant and low dielectric loss.
Working principle of HPA for lithium battery separator coating:
During the operation of a lithium-ion battery, the role of the spacer is to allow lithium ions to pass through the microscopic holes in the spacer, thus completing the charging and discharging process of the battery while keeping the positive and negative electrodes in contact and isolated. The electrons are prevented from passing through. The microporous structure of the diaphragm is therefore very important for the safety performance of the battery. When the cell is overcharged or the internal temperature is too high, the diaphragm pores are closed and the cell is cut off to restrict the movement of ions, thus preventing temperature-induced explosions and other hazards. However, once the temperature reaches the melting temperature of the diaphragm substrate, the diaphragm will completely melt and shrink, the internal circuitry of the cell will be disconnected and the temperature will rise, leading to cell disintegration or even an explosion. Due to its high temperature resistance, safety and self-shutdown properties, coating the surface of the diaphragm with high purity ultra-fine alumina can effectively prevent the diaphragm from melting and the battery from disconnecting due to high temperatures. Therefore, high purity ultra-fine alumina is an ideal material for lithium-ion battery diaphragm coatings, which are currently mainly used for wet lithium battery diaphragm coatings.
