Emerging Trends of Miniaturized Carbon Nanomaterial Based Energy Storage Microdevices

Abstract

Off lately, an increasing reliance on energy-consuming equipment has resulted from the tremendous growth of industry. Owing to the rapid increase in energy use, coupled with the environmental impact of traditional energy supplies, a quest of energy storage device development has begun. Hence, supercapacitors with strategic designs have been developed extensively in last couple of years. This review aims to concise a brief account of the emerging trends in designing of supercapacitors. A snapshot of various materials being used for the development of energy storage device is discussed. New materials such as graphene, carbon nanotubes, perovskites, MXenes, and other nanostructures that can enhance the performance of supercapacitor are being analysed. This review focus primarily on carbon nanomaterial based supercapacitors explored in last couple of years. Electrodes mainly control capacitance, power density, and energy storage, therefore, carbon based electrodes have proven to be significant in this aspect. Various carbon materials give high performance and these have been tabulated in this review for a better understanding. In further, state-of-the-art approaches adapted for fabrication of supercapacitors are also discussed here. Overall, this review gives information about carbon based emerging supercapacitors for the researchers to understand their working, research gap and future prospects.
