A stands for alumina, L stands for LATP, and B stands for boehmite. The thickness of the PE base film is 9um, the thickness of the alumina ceramic coating is 2um, and the oxide solid electrolyte LATP coating is 2um. The ceramic coating is applied on both sides of the PE base film to improve the thermal shrinkage performance of the diaphragm and improve the safety of the battery;
the LATP coating has good lithium ion conductivity and is lighter than the alumina coating at the same thickness. This model can be selected to improve the energy density of the battery. Low internal resistance, high strength, high acupuncture, high air permeability, and good rate performance. It can be used for liquid lithium batteries, solid-liquid hybrid batteries and semi-solid batteries, for button batteries and soft-pack batteries, but not for pure solid-state batteries and sodium batteries. It is more stable when exposed to air, but it is best to operate in a dry room and seal it after use. The orientation of the diaphragm in the full battery is different, and the effect is different, so you need to test it yourself. In lithium metal batteries, it is best to place the LATP coating side facing the positive electrode.
