Beschreibung
Zusammenfassung:	The invention belongs to the technical field of materials, and particularly relates to a preparation method of boehmite with a sheet structure, and application of boehmite. The preparation method of the boehmite with the sheet structure comprises the following steps: mixing aluminum hydroxide and acid liquor, and grinding to obtain aluminum hydroxide slurry; adjusting the aluminum hydroxide slurry to be alkaline, and then adjusting the solid content to obtain a first solution; performing hydrothermal reaction on the first solution to obtain a hydrothermal reaction product; and drying the hydrothermal reaction product to obtain the boehmite with the sheet structure. The boehmite with the sheet structure prepared by the invention has the following characteristics: 1) a high-speed pulverizer or jet mill is not needed for depolymerization; 2) the purity is high, the crystal form is good, and the morphology is complete; and 3) the boehmite can be used as a lithium battery diaphragm material. Meanwhile, the hydroth
