The boehmite coating layer also has the benefit on ionic conductivity the same as the other coating layers, such as Al 2 O 3 layer (0.44 × 10 −3 S cm −1) [ 22 ]. When boehmite is introduced, the charge and electric field associated with the particles interact with the liquid electrolyte leading to the formation of a double layer or space charge.
Boehmite has high purity and high heat-resistant temperature. It is a new type of inorganic lithium battery coating material. Boehmite is also called boehmite and boehmite, and its chemical formula is γ-AlOOH, which belongs to the orthorhombic crystal system of a close-packed cubic structure. It is divided into natural and artificial.
The specific gravity of boehmite is low, and the dosage can be reduced by 25% under the same coating area; the hardness is low, the service life of the coating roller is prolonged by 3-4 times, and the overall economy is better. Boehmite currently accounts for 40-50% of inorganic materials and will reach 70% in 2025.
