China leads global graphite electrode production and sales
On May 28, foreign media said that it is expected that the growth rate of artificial graphite market will reach 4.17% from 2019 to 2024. Currently, the top five giants occupy more than 75% of the market. Among them, it is worth mentioning that at present China is leading the global production and sales of graphite electrodes, with the largest share in consumption and production capacity. More specifically, China is not only one of the largest consumers of graphite electrode materials, but also a country that dominates the production of synthetic graphite.
Lithium battery picture
Graphite electrodes are mainly made of petroleum coke and needle coke, coal tar is used as a binder, and is calcined, compounded, kneaded, pressed, calcined, graphitized, and machined to release electrical energy in the form of an arc in an electric arc furnace The conductors that heat and melt the furnace charge can be divided into ordinary power, high power, ultra high power and anti-oxidation coating according to their quality indicators.
On May 24, it was learned from the Global News Agency (GLOBE-NEWSWIRE) that synthetic graphite is the anode component of lithium-ion batteries, and its usage far exceeds that of metallic lithium. In addition, the anode requires the purity of the coated spherical graphite to exceed 99.9%, which is conducive to improving the battery’s conductivity and enabling stable and efficient charge and discharge.
Graphite anode is mainly made of petroleum coke, coal pitch is used as the binder, and it is made by calcining, batching, kneading, pressing, baking, impregnation, graphitization and machining. It is generally used as the conductive anode of electrolytic equipment in the electrochemical industry, such as anode plates and anode rods for various chemical industries.
Speaking of lithium-ion batteries, I remember Toshiba Japan has produced lithium batteries with nano-violet tungsten oxide powder as the electrode material, which has the advantages of ultra-fast charging speed and ultra-high energy density.
In short, China is not only a country with a large production and sales volume of graphite electrodes, but also the country with the most abundant tungsten reserves.
