The nano alumina ceramic coating provides a skeleton for the flexible seperator, improves the wear resistance of the seperator, prevents lithium dendrite from piercing, reduces heat shrinkage, improves temperature resistance, and the pores are stable with temperature, which can effectively improve the safety performance of the battery.
The main requirements fo rnano alumina powder for seperator ceramic coating are:
(1) High chemical purity (99.5-99.99%);
(2) The particle size is superfine, the particle size distribution is narraw, the deposited pores are uniform, and the pore permeability is high;
(3) The particle shape is like spherical, the crystallinity is high, the specific surface area is small, the oil absorption rate is low, the coating process is effectively improved, and the coating is thin and uniform.
