2. Purity can reach 99.99%, to ensure the cycle performance of the battery.
3. It has good thermal stability and low heat contraction rate.
4. Good mechanical properties, high stretch strength, and high puncture strength.
Product Introduction
Product Introdustion:
High purity ultra fine alumina powder with a purity of 99.99% (4N), the crystal phase of the product is α, θ and γ phases, etc., the average size of the primary particle of the powder is 40 nanometers, and the secondary particle size D50 can be adjusted according to the specific requirements of users. 4N alumina for automotive battery separator has uniform particle size, low water storage, stable chemical properties, good crystal phase stability, insoluble in acid and alkali, and has good sintering activity. A series of high purity aluminas are prepared by different processes. Due to their better physical and chemical properties, the corresponding customers can obtain satisfactory results.
Product feature and application：
4N alumina for automotive battery separator, the main functions of alumina coating are:
Alumina can neutralize the free HF in the electrolyte, improve the acid resistance of the battery, and reduce the gas inside the battery.
The performance of the diaphragm determines the internal resistance and interface structure of the battery, which in turn determines the battery capacity, safety performance, charge and discharge density and cycle performance.
1. The uniformity of the particle size, which can be well bonded to the diaphragm without clogging the diaphragm pore size.
2. The purity of alumina is high, and no impurities can be introduced to affect the internal environment of the battery.
3. The requirement of alumina crystal structure to ensure the compatibility and wettability of alumina to electrolyte.
