Comparative Study of Supercapacitor and Battery for Energy Storage Applications

Energy storage technologies play a crucial role in modern electrical and electronic systems. Batteries and supercapacitors are widely used due to their ability to store and deliver electrical energy efficiently. This paper presents a comparative review of batteries and supercapacitors based on parameters such as energy density, power density, charging time, and lifecycle. The study is based on the analysis of previously published research papers and technical literature. The results highlight that batteries provide higher energy density, while supercapacitors offer higher power density and faster charging capability. The comparison helps in understanding the advantages and limitations of both technologies for different applications.Supercapacitors, Batteries, Energy Storage Systems, Power Density, Energy Density, Electrochemical Energy Storage
