Abstract :
Meaningful effort is being contributed to develop a single functional energy storage system that will close the efficiency gap between batteries and supercapacitors and have high power and energy density. Recent energy technical studies have focused a lot of research on hybrid supercapacitor energy storage devices because of their excellent electrochemical properties, safety, commercial feasibility, and environmental sustainability. As a result, the use of hybrid supercapacitors as energy storage devices is expanding in power, industry, and transportation, particularly in the context of hybrid energy vehicles. A few of the preferred electrode materials utilized in hybrid supercapacitors are carbon derivatives from 0D to 3D, such as activated carbon (AC), graphene, porous carbon, etc. Their availability in reserves, economic feasibility, changeable pore size, and various applications make them viable research focus. Considering this, this paper comprehensively reviews electrochemical supercapacitors and batteries in hybrid energy systems. The three different hybrid supercapacitor types,asymmetric, composite, and battery-type,as well as the electrode materials they incorporate,are the subject of this study. Additionally, the electrochemical characteristics of the porous and graphene-based carbon electrode materials used in asymmetric hybrid capacitors and metal ions hybrid capacitors are reviewed in this work. To further study hybrid supercapacitors for potential use in electric vehicles and other industrial applications, this special review paper`s output will act as a database.
