2023-12-15As is well known, during the manufacturing process of graphite products, the thermal decomposition and condensation of organic carbon based raw materials form porous artificial graphite materials, with a general porosity of around 20% to 30%. Most of them are open pores, which increases the diffusion speed and depth of oxidizing gases, and deteriorates their antioxidant pr
2023-12-15In recent years, data shows that the demand for high-purity graphite in China has been steadily increasing year by year. In 2012, the demand for high-purity graphite in China was 86000 tons. In 2013, the demand for high-purity graphite in China was 97400 tons, a year-on-year increase of 13.24%. In 2014, the demand for high-purity graphite in China was 112000 tons, a year-o
2023-12-14What is graphitization? The so-called graphitization refers to the transformation of non graphite carbon into graphite carbon with a three-dimensional regular ordered structure after high-temperature heat treatment. Originating from the carbon product industry, it is a necessary process for producing graphite electrodes. The graphitization process is aimed at improving the
2023-12-14Graphite bearings are important high-temperature bearings that utilize the self-lubricating, high-temperature resistance, and chemical inertness of graphite materials to operate under high temperature and strong corrosion conditions that ordinary bearings cannot withstand. The main functions of graphite bearings are:
2023-12-13Although graphite has been used as an anode material for power batteries for decades, its large volume, high weight, and physical and chemical limitations make it difficult to meet the high energy density requirements of electric vehicles. Therefore, silicon-based anode materials are gradually replacing graphite and becoming a new direction in the development of power batt
2023-12-131. Low specific surface area: As you mentioned, the specific surface area of waste graphite is usually low, which leads to a decrease in the contact area between the electrolyte and graphite, affecting ion insertion and extraction during the initial charge and discharge process, thereby reducing the initial Coulombic efficiency. Compaction and coating treatment can increas
