This invention discloses a method for preparing nano-boehmite and its application in lithium-ion battery separators, belonging to the field of inorganic nanomaterial preparation technology. The method includes five steps: raw material calcination and activation, preparation of precursor slurry, hydrothermal synthesis reaction, washing and filtration, and drying and depolymerization. Calcination is carried out in a dynamic calcination furnace, whose exhaust mechanism can promptly remove water vapor. During discharge, the switching mechanism automatically opens the discharge cover, achieving continuous production with no material sticking to the wall and no residue. The obtained nano-boehmite is characterized by low sodium content, uniform particle size, and good dispersibility. This material can be formulated with binders and other agents to form a ceramic coating slurry. After coating and drying, a robust nano-ceramic coating is formed on the surface of a polyolefin-based membrane. This coating significantly improves the thermal stability, electrolyte wettability, and puncture resistance of the separator, thereby improving the battery's safety performance and cycle life.
