Guest Edited by Zhaojun Han, Ruopian (Sophie) Fang, Dewei Chu and Da-Wei Wang (all from University of New South Wales, Australia).
Supercapacitors are important electrochemical energy storage devices that can deliver high power, fast charge/discharge rate, long lifespan and safe operation. The last few decades have witnessed significant progress in supercapacitors for clean and sustainable energy applications. Depending on charge storage process, supercapacitors can be classified as electric double-layer capacitor (EDLC) or pseudocapacitor.
This themed collection features work covering all aspects of supercapacitors, including electrochemistry, electrode materials, electrolytes, performance evaluation, device design and fabrication, and applications.
