Recent progress in carbon-based nanoarchitectures for advanced supercapacitors

Abstract

Supercapacitors, possessing high power densities, have been supposed to be one of the promising energy storage devices. Among various electrode materials of supercapacitors, carbon materials with porous nanostructure are considered as the emerging and promising candidates. This feature article reviewed the recent advances in different dimensional carbon-based nanoarchitectures for supercapacitors and particularly addressed the novel synthetic strategies to improve the electrochemical performances and corresponding theoretical foundations. The state-of-the-art progress was discussed, and diverse challenges for the electrochemical properties of carbon-based materials were propounded. Furthermore, perspectives for the design and assembly of advanced carbon-based nanoarchitectures for the supercapacitor electrode materials were highlighted.

“…Therein, the electrochemical energy storage systems (EESs) are being accredited as one of the most potential devices for efficient energy storage [5][6][7]. As the typical representative, supercapacitors (SCs) have widely aroused scientific and technological interests due to their high-power output, fast charge-discharge kinetics, and long cycle life [8][9][10]. These advantages make them become the favorable candidates for applications of portable electronic device or hybrid electric vehicles [11,12].…”

“…Supercapacitors, on the other hand, have a relatively lower energy density, but they offer a fast charge/discharge rate, good stability, very long life-cycles, and have a high power density. [2][3][4] These unique advantages of supercapacitors make them desirable as power sources either individually or combined with other energy storage devices to build a hybrid power supply system. Lower energy densities are the biggest downside of these devices when compared to batteries.…”

Preparation and Electrochemical Performance of Hollow Activated Carbon Fiber Self-Supported Electrode for Supercapacitor

“…Supercapacitors, a promising power source, have attracted intensive attention since they can provide energy density by orders of magnitude higher than dielectric capacitors, providing greater power density and longer cycling ability than batteries [1][2][3][4][5][6]. Electrode materials have a great effect on the electrochemical properties of supercapacitors.…”
