Huaming Gaona high-end lithium battery separator alumina project put into operation

The purity, particle size and morphology of the ceramic alumina used for coating the separator are very high. The products in Japan and South Korea are more mature, but the price is more than double that of the domestic one.

In the coated diaphragm, the ceramic coated diaphragm is mainly for the power battery system, so its market growth space is larger than that of the rubberized diaphragm, and the market demand for the core material ceramic alumina will be greatly improved with the rise of the ternary power battery.

The purity, particle size and morphology of the ceramic alumina used for coating the separator are very high. The products in Japan and South Korea are more mature, but the price is more than double that of the domestic one.

At present, there are many companies in China that are developing ceramic alumina, hoping to gradually reduce import dependence.

On March 30th, Jiande Huaming Gaona New Materials Co., Ltd. invested a total of 3,000 tons of lithium battery diaphragm alumina project jointly invested by Shanghai Huaming High Technology (Group) Co., Ltd. and Shanghai Gaona Industrial Co., Ltd. Officially put into operation.

The project is implemented by the Jiande Sub-center of the Superfine Powder National Engineering Research Center. The total investment is 25 million Yuan. It was started in October last year. It mainly uses domestic alumina powder for purification and grading. Developed to meet the coating materials for high-end lithium battery separators.

General Manager Wei Gao commented that the main feature of alumina for lithium battery separator is that its particles are relatively uniform, providing very good conditions for the large capacity of future batteries, and providing a good technology guarantee for fast charging and large-capacity batteries in the future.
