Abstract

Pseudocapacitive materials exhibit capacitor responses resulting from the reversible redox reactions that occur at or near the surface of a material in contact with an electrolyte, or are not limited by the solid-state ion diffusion. Since the energy density and specific power as well as the cycling life of energy storage devices are very important characteristics, how to achieve the high energy density at high charge–discharge rates with long cycling life is the main challenges in developing electrode materials of supercapacitors. Therefore, this talk will give a brief background on the required characteristics of electrode materials for supercapacitors, especially materials designs of pseudocapacitors employing both aqueous and organic electrolytes. Some examples will be provided, emphasizing the role of structure and microstructure on the electrochemical properties of the electrodes.
