Research progress on the preparation and application of needle coke
Needle coke is a silver-white solid carbon material with metallic luster, which has obvious needle-like texture structure when observed under a microscope. Because of its low thermal expansion coefficient, high electrical conductivity, and high chemical stability, it is widely used in high-performance graphite electrode materials, lithium ion batteries, electrochemical capacitors and other fields.

Performance indicators of needle coke
At present, needle coke is mainly used to manufacture graphite electrodes for ultra-high power electric furnace steelmaking. This kind of electrode has high electrical conductivity, high mechanical strength, excellent thermal shock resistance and oxidation resistance. Graphite electrodes are made of needle coke as the main material and medium-temperature pitch as the binder, after forming, roasting, impregnating and graphitizing processes.
