A stands for alumina, L stands for LATP, and B stands for boehmite. The thickness of the PE base film is 9um, with a 2um boehmite ceramic coating on one side and a 2um boehmite ceramic coating + 1um oxide solid electrolyte LATP coating on the other side.
The advantages of this diaphragm are high strength, high air permeability, high heat shrinkage temperature, good rate performance, and high battery thermal runaway temperature. The 9um PE base film is stronger than the 7um base film: compared with alumina, the density of boehmite is smaller, and the same mass of AIOOH is coated with 25% more area than high-purity AI203: and the boehmite coating has high flatness and low internal resistance; the double-layer boehmite coating makes the diaphragm heat-resistant at a higher temperature: good compatibility with organic solvents and good wettability; the LATP coating has good lithium ion conductivity, and the gram weight is lower than that of the alumina coating at the same thickness, which can improve the energy density of the battery to a certain extent. It can be used for liquid lithium batteries, semi-solid lithium batteries, button batteries and soft-pack batteries, but not for pure solid-state batteries and sodium batteries. It is stable when exposed to air, but it is best to operate in a dry room and store it sealed after use.
