The Influence Of Boehmite On Separators And Batteries

Boehmite (γ-AlOOH) is the main component of bauxite, and It is an important chemical raw material with a unique crystal structure. It is widely used in many fields such as catalysts and carriers, paper fillers, inorganic flame retardants, etc. In particular, it can be used as a precursor to prepare aluminum oxide, which is widely used in ceramics, electronics, adsorption, and catalysis and has broad application prospects. At present, the preparation of inorganic nanomaterials with specific morphology has become a research hotspot in materials science.

1. Overview of boehmite

Boehmite, also known as boehmite and boehmite, has a chemical formula of γ-Al2O3·H2O or γ-AlOOH, which belongs to the orthorhombic system. γ-AlOOH is composed of many A1O6 octahedrons. Al is in the center of the octahedron, and O is at the apex of the octahedron. The octahedrons form a double chain through coplanarity, and the vertices form a three-dimensional skeleton structure. The crystal structure is shown in the figure below.

2. What are the advantages of boehmite as a lithium battery separator coating material？

Boehmite has excellent insulation, chemical, and electrochemical stability, heat resistance, etc. It can improve the thermal stability of the separator at a lower coating thickness, improve the safety of lithium-ion batteries, and improve the battery rate Performance and cycle performance.

3. What are the effects of boehmite on the separator and battery?

The boehmite products produced by ZC-TECH can be used for both ternary lithium batteries and lithium iron phosphate batteries.
