PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC for iron removal of artificial graphite raw materials are divided into coal measures, petroleum and coal and petroleum mixed system three categories, asphalt is the binder. Coal measure needle coke, petroleum needle coke and petroleum coke are the most widely used. Different coke, such as petroleum needle coke and coal needle coke, domestic coke and imported coke, the price difference is large, is also the key point of cost control.
Generally speaking, the negative electrode with high specific capacity uses needle coke as raw MATERIAL, and the negative electrode with ordinary specific capacity uses cheaper petroleum coke as raw material. Different raw materials are important factors to determine the performance of PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC treatment of artificial graphite. It affects the specific capacity, cycle life, multiplicity and compaction density of artificial negative electrode. If isotropic coke is selected, the product performance can be improved.
At present, the trend of the industry is to choose low cost coke to make artificial graphite, PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC process control to improve performance, reduce cost, reduce quality. In the production of large-size high-power and ultra-high-power graphite electrodes, carbon enterprises usually choose high-quality oil series needle coke as the main raw material. At present, coal series needle coke is the main material.
