Coal tar and light oil are by-products from the coking process at steel mills, accounting for 3 to 4% of our coke production output. Coal tar and light oil purchased by CSCC from CSC Group are distilled and purified at the Coal Chemical Manufacturing Department to manufacture a number of major products, such as soft pitch, naphthalene, refined naphthalene, benzene, and toluene. The products are chemical products and are not genetically modified products.
As green energy, energy conservation, and carbon reduction have become issues of concern nowadays, there is a growing demand for parts and components related to electric vehicles and energy storage systems, which has led to the further development of soft pitch, a main product of coal tar at CSCC. As soft pitch is used in anode materials for lithium-ion batteries and ultra-high power electrodes, the traditional coal chemical industry is gradually extending and pivoting to the high-tech carbon material and green energy industries.
With countries around the world actively investing in the development of new energy industries, lithium-ion batteries have become the mainstream energy storage medium for mobile devices, thanks to their relatively good energy density. Electric vehicle batteries have become a current market trend, owing to the rollout of new energy vehicle incentive policies in China and the European Union over the years. The modularization of power batteries with supercapacitors, which are regarded as new generation high-power energy storage components, can give rise to high output power from these batteries. With a commitment to developing high-value green carbon materials, CSCC has developed anode materials for high-energy and high-power lithium-ion batteries, which are widely used in new energy industries.
