The glassy carbon (GC) is a new type of carbon material ,it’s similar to glass and in the carbon structure, and it is also a new type of amorphous carbon structure material. The GC is made of biological resin carbon through high temperature pyrolyzation and carbonization . It does not contain harmful substances on the human body, high purity carbon. Glassy carbon is characterized by its high hardness and permeability due to its port morphology and structural characteristics similar to that of glass. Glass carbon has high strength, hardness and elastic modulus. It can be used to make high speed typewriter wheel and record. Glass carbon has many superior properties: density is small, about 1.3g/cm3; 3800℃high temperature resistance; anti penetration;…
In order to enhance the oxidation resistance of graphite mould and prolong its service life, it is necessary to reduce the gasification reaction rate of graphite material at high temperature. Under normal circumstances, there are three factors affecting the gasification reaction of graphite materials: (1) graphitization degree of carbon graphite material increased, the activity of gas decreased, gasification reaction rate was slow. The higher the heat treatment temperature of carbon materials, the higher the temperature of the starting oxidation. (2) the state of the surface of the structure is loose and porous carbon graphite material, easy to react with the gas, and the surface of carbon graphite material, not easy to react with gas. For example, after 3200 degrees of…
Flow battery is to achieve large-scale renewable energy application of new green secondary battery two, the performance of electrode materials has important significance for the practical application of the flow battery, PAN based graphite felt electrode material is the preferred flow battery, in order to further improve the hydrophilicity and electrochemical activity of the modified Shi Mozhan electrode materials, graphite related research in recent years the carpet has become a hot spot. Energy storage technology is very conducive to the balance between energy production and consumption between the control in power, plays an important role in the integration of renewable energy and other areas, as one of the electrochemical energy storage technology flow battery, the redox flow battery, with current…
