Graphite electrode is mainly made from petroleum coke and needle coke an make the coal tar pitch as the binder, through calcination, mixing, kneading, pressing, baking, graphitization, and machining , it is a conductor in an electric arc furnace to form arc release electricity for heating and melting of the charge, it can be divided into ordinary power, high power and ultra high power according to the quality index level. The graphite electrode mainly includes ordinary power graphite electrode, oxidation resistant coating, graphite electrode, high power graphite electrode and ultra high power graphite electrode . In order to make the graphite electrode with a series of physical and chemical properties when we used it , the asphalt binder decomposition and…
Similar to the super capacitor, ultra-thin graphene nano materials excellent conductivity can form two-dimensional conductive contact with the particle electrode active material of lithium ion battery, constructing three-dimensional conductive network in the electrode, which can greatly improve the battery performance. The experimental results show that graphene conductive additives can greatly reduce the internal resistance of battery, improve the high rate charge and discharge performance of the battery, and prolong the battery cycle life; also can increase the capacity of active material g play, so as to improve the battery capacity; can also reduce the amount of conductive agent, is conducive to the design of high energy density batteries; in addition, containing graphene the conductive agent battery in high rate…
1. Brief introduction of graphite electrode Graphite electrode is mainly in the petroleum coke and needle coke, coal tar pitch as binder, calcinations, mixing, kneading, pressing, baking and graphitization, and made the processing machine, is a conductor in an electric arc furnace to form arc release electricity for heating and melting of the charge, according to the quality index level, can is divided into ordinary power, high power and ultra high power. 2. graphite electrode instructions A. wet graphite electrode, use before drying. B. Remove the foam protection cap on the spare graphite electrode hole and check the integrity of the screw inside the electrode hole. C. compressed air oil and water to clean up the spare graphite electrode surface…
