Financial sector 2025 Year 4 Moon 2 According to news reports, information from the National Intellectual Property Administration shows that Shijiazhuang Shangtai Technology Co., Ltd. has filed an application for a patent titled: “ A composite material based on a graphite particle core with a porous carbon shell, its preparation method, and applications. ” the patent, publication number CN 119742355 A , the application date is 2025 Year 1 Moon.
The patent abstract discloses a composite material based on a graphite particle core surrounded by a porous carbon shell, as well as a method for its preparation and applications. This invention falls within the technical field of negative electrode materials for lithium-ion batteries. Specifically, the porous carbon accounts for a certain percentage by mass of the composite material. 2% 50% ; The specific surface area of the composite material is 20 1458 m²/g , the total pore volume is 0.01 0.74 cm³/g The proportion of micropore volume to total pore volume is: 80% 96% , with an average pore size of 1.62 2.33 nm This invention addresses the issues of poor conductivity, slow lithium-ion diffusion rate, and significant volume expansion by... Cardiovascular disease Silicon-carbon material is coated on the surface of graphite particles, as opposed to the conventional method of directly applying it... Cardiovascular disease Compared with graphite, silicon-carbon materials significantly improve the rate performance and cycle stability of negative electrode materials. This invention is suitable for the preparation of lithium-ion battery negative electrode materials.
