The GM series Alumina Powder For Lithium Battery Diaphragm produced by Xiangrun are applied as ceramic coatings on the positive and negative barrier films of lithium batteries. This GM alumina powder plays the role of heat resistance, high temperature resistance and insulation, thus preventing the power battery from being overheated due to excessive temperature and short circuit of the diaphragm.
Performance characteristics of Alumina powder for lithium battery diaphragm:
(1). All inorganic ingredients, high purity, non-toxic and harmless, green and environmentally friendly, in line with national standards and international environmental protection requirements.
(2). It has good high temperature resistance, and it is a ceramic separator with excellent insulation performance.
(3).The particle size is moderate. The average particle size is about 500 nanometers. After applying this release agent, it can not only withstand high temperature and insulation, but also block the film hole. And it does not affect the back and forth movement of the lithium battery between the positive and negative electrodes and never shortened the service life of lithium batteries.
(4). Good dispersion performance and good suspension performance.
