The raw materials of artificial graphite are divided into three categories: coal series, petroleum series and coal and petroleum mixed series, and asphalt is the binder. Coal series needle coke, petroleum series 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, but also the key point of cost control,PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC can save costs.
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 determining the performance of artificial graphite, affecting the specific capacity, cycle life, doubling rate and compaction density of artificial negative electrode, such as isotropic coke. PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC field can improve product performance.
At present, the trend of the industry is to choose low-cost coke, improve performance, reduce cost and guarantee quality through PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC process control. Carbon enterprises producing large-size high-power and ultra-high-power graphite electrodes often choose high-quality oil-series needle coke as the main raw material coke. At present, coal series needle coke is the main source of needle coke.
