Supercapacitors are the most maintainable energy conservation devices and have pulled in broadconsideration due to long cycle life, excellent power density, stability and integrity. As of now, allresearchers are concentrating on how the energy density can be improved while retaining high powerdensity, fast charge or discharge and cycling stability. In this review, we look into the most broadlyused electrode materials based on carbon nanotubes (CNTs), graphene, activated carbon, carbonquantum dots, porous carbon, metal oxides, conducting polymers, composite hybrid materials,asymmetric hybrid materials, battery type electrode materials, etc. for designing various types ofsupercapacitors and their characteristic performance. This review would help to understand the recentadvancements progressed in electrode materials for applications in electrochemical supercapacitors.
