Ceramic coated special separator: It is
based on PP, PE or multi-layer composite diaphragm. The surface is coated with
a layer of nano-scale aluminum oxide material. After special treatment, it is
tightly bonded to the substrate. Significantly improve the high temperature
performance and safety of lithium ion batteries. Ceramic coated special
diaphragms are especially suitable for power batteries.
Performance requirements:
1. Uniform particle size, which can be
well bonded to the diaphragm without clogging the diaphragm aperture.
2. The purity of alumina is high, and
impurities cannot be introduced, which affects the internal environment of the
battery.
3. The requirements of the crystal
structure of alumina ensure the compatibility and wettability of alumina to the
electrolyte.
