Supercapacitors: Asymmetric Supercapacitor Electrodes and Devices (Adv. Mater. 21/2017)

The development of asymmetric supercapacitor (ASC) electrodes and devices, which offer enhanced voltage output and high energy densities is reported by Yeonwoong Jung, Jayan Thomas, and co-workers in article number 1605336. Newly emerging transition-metal dichalcogenides (TMDs) and MXene materials are discussed for their potential candidature. Several flexible ASC designs (sandwitch-type, fiber-type) with rational configurations offer exceptional properties that enable them for future flexible energy-storage applications.
