What are the Types of Electrode Materials in Supercapacitors?
There are several types of electrode materials commonly used in supercapacitors, each benefiting from catalytic enhancements:
1. Carbon-based materials: Activated carbon, graphene, and carbon nanotubes are widely used due to their high surface area and conductivity. Catalysts can improve the surface functionalization and electrochemical properties of these materials. 2. Metal oxides: Transition metal oxides like ruthenium oxide, manganese oxide, and nickel oxide offer high capacitance. Catalysts can enhance the redox activity and stability of these materials. 3. Conducting polymers: Polyaniline, polypyrrole, and polythiophene are known for their high capacitance and flexibility. Catalysts can improve their conductivity and mechanical properties.
