摘要：

In this study, a flexible hybrid film based on single-wall carbon nanotubes (SWNTs) was fabricated. The SWNTs@MnO2/Polypyrrole (PPy) film was used as a supercapacitor electrode without binders to achieve high capacitance. The binder-free electrode with SWNT and PPy layers improved the conductivity of the electrode materials, as well as the ion diffusion rate and charge-transfer resistance, thus achieving excellent electrochemical performance compared with SWNTs@MnO2 electrodes. The specific capacity was 351 F g(-1) based on the total weight of the electrodes with energy density of 39.7 Wh kg(-1) and power density of 10 kW kg(-1). Our study could provide a novel and facile strategy for the development of high-performance energy storage devices. (C) 2014 Elsevier Ltd. All rights reserved.
