Recently, Topfine New Materials Co., Ltd. and Gangfeng New Materials Co., Ltd., subsidiaries of Inter-China Chemical Co., Ltd. , were jointly granted an invention patent by the China National Intellectual Property Administration for “A Preparation Method of Lithium Ion-Sieve Particles with High Adsorption Capacity.”

This patented method features a simple and environmentally friendly process with low production cost. The resulting lithium ion-sieve particles exhibit high porosity, high adsorption capacity, fast adsorption rate, and long cycle life. They can be directly applied in lithium extraction from salt lake brines, seawater, oilfield brines, and underground lithium-containing brines.

As of now, Inter-China Chemical and its subsidiaries have filed 60 patent applications, among which 15 invention patents and 1 utility model patent have been granted. Gangfeng New Materials will continue to strengthen research and development of titanium-based new materials, driving innovation to develop more advanced technologies and products, and providing strong material support for the growth of China’s high-end manufacturing sector.
