The role of mass transport pathway in wormholelike mesoporous carbon for supercapacitors

Abstract

In the present paper, we demonstrate the importance of the role of a mass transport pathway (MTP) in wormholelike mesoporous carbon (WMC) through studying the ion diffusion behaviors within two different wormholelike mesopore networks with and without MTP. Our results reveal that the introduction of MTP is very helpful in improving ion diffusion properties. The as-prepared WMC with a MTP of ca. 9.7 nm exhibits notably better electric double layer performance as compared to the conventional WMC without a MTP. For example, even at the quick sweep rate of 50 mV s−1, the surface specific capacitance of the former is 21.6 μF cm−2, which is almost 4 times as high as that of the latter (5.5 μF cm−2).
