A Study on Electrochemical Supercapacitors

The reduction of fossil fuels and their destructive impacts on the environment has made researchers focus more on using clean and renewable energy sources. Various energy storage systems such as batteries, conventional capacitors, solar cells, and supercapacitors (SC) are being developed, and supercapacitors have received more attention in recent years. Based on energy storage mechanisms, electrochemical supercapacitors have a higher power density than batteries and solar cells. Also, they have a higher energy density than ordinary capacitors due to their unique energy storage mechanism. This paper focuses on electrochemical supercapacitors.
