Recently, the method for preparing "a high adsorption capacity lithium-ion sieve particle" jointly submitted by Topfine New Materials Co., Ltd., a subsidiary of Inter-China Chemical Co., Ltd., and Gangfeng New Materials Co., Ltd., has been granted an invention patent by the Intellectual Property Office.

The preparation process of this patent is simple, environmentally friendly, and cost-effective. The lithium-ion sieve particles obtained through this method have advantages such as high porosity, high adsorption capacity, fast adsorption rate, and long cycle life. They can be directly used for lithium extraction from brine in salt lakes, seawater, oilfield brine, lithium-containing brine in underground sources, and more.

As of now, Inter-China Chemical and its affiliated enterprises have applied for 60 patents, with 15 granted invention patents and 1 utility model patent. Gangfeng will continue to strengthen the research and development of titanium-based new materials, innovatively develop more new technologies and products, and contribute innovative materials to support the development of high-end manufacturing.
