Performance enhancement of graphene/GO/rGO based supercapacitors: A comparative review

Due to the surge in requirement for reliable energy storage, search for materials capable of rendering perfect electrochemical performances is going on at a great rate. Even though supercapacitors have higher power density than batteries, they are still restricted by low energy density and low-capacity retention. Essential fuel sources like internal combustion engines, power devices and batteries function admirably as a consistent source of low power, yet can't productively deal with top power demands or recover energy since they release and re-energize slowly. Recently, the quick development in graphene-based supercapacitors has arrived at where there is a requirement for devices with definite adaptability, which will be a fundamental benefit in innovative electronic devices. Different materials are being tested to ensure the suitable properties. Graphene having unique properties like wide surface area, high conductivity, is considered as a potential candidate for the usage as building material of superconductors. In this paper we studied various aspects of graphene-based superconductors, their types, metal/ non-metal/ polymer doping as well as oxides & reduced oxides of graphene incorporated superconduc-tors. By summarizing we tried to compare the processes followed by the researchers and find out which would be the most suitable way to get the best electrochemical performance.
