Boehmite used in lithium battery separator

The most important use of boehmite is to prepare alumina powder after calcination.

This is firstly because boehmite can easily adjust the preparation process conditions to obtain a variety of products with different morphologies. Secondly, because the boehmite structure is stable, only the crystal form changes before and after calcination, while the morphology of the product remains unchanged, and alumina products with the same morphology can be obtained. In recent years, various nanomaterial preparation methods have emerged in an endless stream, and various morphologies of boehmite have also been prepared one after another. A new favorite in the field of materials.

In addition to being used as an important precursor material for the preparation of different crystalline aluminas, boehmite itself is also used in adsorption separation, catalysis, composite materials, liquid crystal, medicine, optics, sensors, lithium batteries with its unique chemical, optical, mechanical and other properties. Diaphragm coating materials and other fields are widely used.

Among them, the application of boehmite in lithium battery separator has outstanding advantages. Under the influence of market competitiveness and rising raw material and labor cost prices, the price of my country's boehmite industry may maintain an upward trend. It is predicted that with the upgrade of the diaphragm technology war, the opportunity for the boehmite coating market will come.
