Product Description
Kelin Super Capacitor active carbon powdered 300 mesh Adsorption Decolorize Industry Grade Coal Based Activated Carbon Powder
The formation process of supercapacitor carbon involves several steps. First, a suitable carbon source, such as coconut shells or activated carbon powder, is chosen. The carbon source is then heated to a high temperature in an oxygen-free environment, a process known as pyrolysis. This pyrolysis process removes impurities and converts the carbon source into an amorphous carbon material.
Next, the amorphous carbon material undergoes a series of activation processes to increase its surface area and porosity. Activation can be achieved through chemical or physical methods. Chemical activation involves treating the carbon material with chemicals such as phosphoric acid or potassium hydroxide, which removes the amorphous carbon and creates a highly porous structure. Physical activation, on the other hand, involves treating the carbon material with steam or carbon dioxide at high temperatures, resulting in the formation of pores.
After activation, the carbon material is then subjected to a post-activation process called oxidation. During oxidation, the carbon material is heated in the presence of oxygen or air, allowing functional groups such as carboxyl or hydroxyl groups to be introduced onto the carbon surface. These functional groups enhance the electrochemical properties of the carbon, improving its capacitance and energy storage capabilities.
Finally, the oxidized carbon material is washed and dried to remove any remaining impurities or chemicals. The resulting supercapacitor carbon exhibits a high surface area, a porous structure, and excellent conductivity, making it ideal for use in supercapacitors.
In summary, the formation process of supercapacitor carbon involves the selection of a suitable carbon source, pyrolysis to obtain amorphous carbon, activation to increase surface area and porosity, oxidation to introduce functional groups, and final washing and drying.
