Battery technology is well-established and widely used technology, but they offer several disadvantages such as weight, volume, high internal resistance, power density, short-term negative feedback. A new technology is rising in this area i.e., the supercapacitor, it has a very effective capability to come up in major advances in energy storage. Supercapacitors are controlled by the same basic as conventional capacitors but use a greater number of electrodes and smaller dielectrics to obtain greater power. They offer short-term response, power, low weight, low volume, and low internal resistance that make them suitable for most applications. This paper summarizes the different types of supercapacitors, the relevant quantitative modeling areas, and the future of supercapacitor research and development.
