MUMBAI, India, Oct. 31 -- Intellectual Property India has published a patent application (202424054820 A) filed by Advanced Lithium Electrochemistry Co. Ltd., Taoyuan City, Taiwan, on July 18, 2024, for 'composite anode material and preparation method thereof.'
Inventor(s) include Shu-Jui Chang; Nae-Lih Wu; and Han-Wei Hsieh.
The application for the patent was published on Oct. 31, under issue no. 44/2025.
According to the abstract released by the Intellectual Property India: "A composite anode material (1) is provided. The composite anode material (1) includes a graphite (10), a plurality of silicon particles (20), and a carbon coating layer (30). The graphite (10) is pretreated with surface modification through an organic polymer. The plurality of silicon particles (20) are coated on the graphite (10). The carbon coating layer (30) is coated on the graphite (10) and the plurality of silicon particles (20). The carbon coating layer (30) is formed by carbonizing the organic polymer through a heat treatment. A preparation method of the composite anode material (1) includes steps as follows. Firstly, a graphite (10) and an organic polymer are mixed to form a first composite particle. Secondly, the first composite particle and a plurality of silicon particles (20) are mixed to form a second composite particle. Finally, a heat treatment is performed on the second composite particle to form the composite anode material (1)."
