Supercapacitors: Review of materials and fabrication methods

It is hoped that supercapacitors will power devices in the future. Future hybrid electric automobiles and other electrical infrastructure will benefit from these parts. Improving supercapacitors' energy and power densities is essential to tap into their potential fully. Improvements in electrode materials and fabrication methods could solve this problem. The development of better supercapacitor electrodes has necessitated the production of several different materials during the past few years. It is prudent to investigate all facets of supercapacitor units due to the rapid development of technology. This paper reviews a brief overview of the broad spectrum of current supercapacitors. Modern fabrication methods, materials for supercapacitors, and their future potential are analysed. Also discussed the main technical obstacles that could hinder future growth efforts in various industries.
