New Materials for Low-carbon Supercapacitors: Latest Developments and Perspectives

Abstract

We present the state-of-the-art regarding the materials used in the construction of low-carbon supercapacitors. Electrode, electrolyte, binder, separator, and current collector constructing elements of supercapacitors are separately considered and the latest progress in using low-carbon materials is reviewed. In general, the trend of using green constructing materials has overshadowed this study, and in some cases, the life cycle of the substances is also taken into consideration. In perspective, aiming at low-carbon supercapacitors may force the producers to a trade-off between high performance and impact on the environment.
