As a strategic partner of FeisTech International's graphite anode material canister business in China, Shijiazhuang Zhongdong Carbon Co., Ltd. was established on July 4, 2007, located in Dongwangshe Village, Jingcheng Mining District, Shijiazhuang City. The registered capital of the company is 6.5 million yuan, and it currently has 240 employees. It mainly produces graphite field carbon products and pre carbonization of Li electric negative electrode materials, and has 8 utility model patents. In 2020, it was rated as a national high-tech enterprise and obtained a B-level certificate from Hebei Province Industrial Enterprise Research and Development Organization. The company currently has 2 ring type carbon roasting furnaces, 1 carbon rod product machining production workshop, a graphite crucible production capacity of 160000 sets, and a pre carbonization processing capacity of 15000 tons/year for negative electrode materials.

Graphite canister products are made by mixing graphite particles with asphalt as the main material, and have the characteristics of high temperature resistance, strong thermal conductivity, good corrosion resistance, and long service life. During high-temperature use, the coefficient of thermal expansion is small, and it has certain strain resistance performance for rapid cooling and heating. It has strong corrosion resistance to acidic and alkaline solutions, excellent chemical stability, and does not participate in any chemical reactions during the graphitization process. In order to better save resources, increase product added value, and improve the reuse of thermal energy in the production process, we have introduced a pre carbonization process for negative electrode materials, fully utilizing the thermal energy in the roasting process. Lithium ion negative electrode materials must be graphitized before use, but conventional negative electrode materials require 17000KWh of electricity per ton of negative electrode material during the graphitization process. By pre carbonizing the negative electrode material during the production of graphite, we can save 30% of the energy consumption during the graphitization process of the back-end negative electrode material, effectively promoting carbon reduction.
