| titleOfInvention | A kind of safety coating, its preparation method and use |
| abstract | The present invention relates to a safety coating, its preparation method and use. The security coating of the present invention includes a modified soft inorganic compound; the elements in the modified soft inorganic compound include IIA element and/or IIIB element. In view of the high hardness of the ceramic itself in the prior art, it is easy to scratch the surface of the roll during the rolling process after coating, which affects the life of the equipment; at the same time, the compatibility between the ceramic and the active layer of the negative electrode surface is poor, resulting in a large interface impedance. Reduce the migration rate of ions, which ultimately affects the battery cycle life and low temperature performance. By coating the surface of the negative electrode pole piece with a soft inorganic compound coating, the invention can improve the problem that the lithium dendrite pierces through the diaphragm and causes the internal short circuit of the lithium ion battery; in the battery production process, damage to the battery manufacturing equipment can be reduced, Also, the impact on battery cycle life and low temperature performance can be reduced. |
