Abstract

Emerging demand for energy storage devices stimulates the research and development activities on supercapacitors due to its unique advantages (power delivery and cycling performance) over secondary batteries. A wide range of materials, which include metals, metal oxides, chalcogenides, carbon allotropes, and their hybrid/composite architectures, have been extensively investigated as electrode materials for supercapacitor applications. It was found that the nanostructure of the above mentioned material showed superior electrochemical performances compared to their bulk forms. As a result, a wide range of nanomaterials have been extensively investigated as the electrode material in all segments (employing pseudo and electric double layer capacitive mechanisms in symmetric and asymmetric configurations) of supercapacitors. Recent research interest in supercapacitor materials turned into their synthesis/fabrication by employing various sustainable/green strategies, which include the consumption of renewable resources, exploration of waste/recycled products as feedstocks, and the utilization of materials/processes with less environmental impacts. Thus, the present chapter summarizes the synthesis and their applications of various renewable resource-based green nanomaterials for supercapacitor applications.
