Review of supercapacitors based on graphene: Advancements and limitations.

Background/Objectives: Graphene is a revolutionary discovery. It is credited as the lightest and strongest material available in the world. Its high-power density and energy density it is being considered a potential candidates as electrodes in supercapacitors, which in themselves are new to the market. The main objective of this paper is to highlight the usage and benefits of graphene in supercapacitors. Methods/Statistical analysis: Super-capacitors are barely a new technology. Due to its unique property of handling high power and high rate of charging or discharging, it is seeming as a solution for many problems. It is observed that using graphene in supercapacitors makes it more efficient and reliable. Therefore, here an attempt is made to review the effects and advantages of graphene-based supercapacitors. Findings: The graphene-based supercapacitors are highly efficient and able to handle more power and energy density as compared with the conventional ones. The numerous beneficial properties of graphene such as high conductivity, lightweight, high-power density, high energy density, high surface area, etc. make it the most suitable candidate for the electrode used for supercapacitors and have opened the gates for more graphene and other carbon nanostructure-based supercapacitors. Improvements/Applications: Supercapacitors prove themselves as an important element in the field of the flexible electronics industry. It is observed that the usage of graphene-based electrodes improves the performance of super-capacitors. Therefore, applications which involve flexible and stretchable consumer electronics graphene-based supercapacitors are highly desirable. [ABSTRACT FROM AUTHOR]
