Materials Challenges for Supercapacitors

Supercapacitors are considered as one of the most important candidates in the domain of energy storage devices for the forthcoming generations. These devices, known for high power density and long cycle life, have earned their significance in numerous applications (in portable electronics, automobile vehicles, stationary power stations and backup power supplies, etc.) This Special Topic of APL Materials entitled "Materials Challenges for Supercapacitors" covers recent advances in supercapacitors such as electrical-double-layer supercapacitors (EDLCs), pseudocapacitors and new configurations for hybrid supercapacitors. This Special Topic also highlights materials development and challenges, with a focus on electrode materials, electrolytes, interfaces, and rational design targeted towards high-performance supercapacitors.
