Product introduction:
Boehmite (Boehmite) , also known as boehmite, has a molecular formula of γ-AlOOH (hydrated alumina), and diaspore, whose main component is α-AlO(OH), is the main component of bauxite. 99.9% Boehmite powder usual use to diaphragm coating due to it has good insulation.
Boehmite is used in the production of lithium battery separators, which are the safety guards of lithium batteries and have a high-efficiency flame retardant effect. It is mainly used in the production of battery separators for lithium batteries, catalysts for petroleum refining, high temperature resistant halogen free flame retardants, electronic industrial products, white pigments and other products.

Advantage of application:
1. Under the premise of low coating thickness, boehmite powder used to Diaphragm coating, and it can significantly improve the thermal stability of the diaphragm, enhance the safety of lithium battery, improve the multiplier performance and cycling performance of the battery, and at the same time, the thinner coating thickness is helpful to improve the volume energy density and weight energy density of lithium ion battery.
2. Compared with alumina, AlOOH has the characteristics of high heat temperature, good compatibility with organic matter, low hardness can reduce mechanical wear, and has advantages in cost.
3. The appearance of ALOOH is white, with high purity and good dispersibility. It does not introduce impurities, and does not affect the internal environment of the battery. The function of breaking current conduction and reducing the closed-cell temperature of the diaphragm greatly improves the safety performance of lithium batteries; it has excellent thermal conductivity, which can effectively solve the problem of poor thermal conductivity of PP/PE materials; it has excellent flame retardant performance, effectively preventing a wide range of Burn or even explode.
Boehmite vs Alumina:
At present, alumina is more widely used in separators. However, it is worth noting that the hardness of alumina is relatively large, so during the cutting and coating process, the mechanical wear is large, and the cost is higher than that of boehmite. The boehmite has the characteristics of high heat resistance temperature, good compatibility with organic matter, low hardness, which can reduce the wear and tear of machinery, and has advantages in cost.
