1Facile construction of novel CoMoO_4 microplates@CoMoO_4 microprisms structures for well-stable supercapacitors显示文摘A simple and controllable strategy has been developed to fabricate CoMoO_4 microplates/CoMoO_4 microprisms(CMCMs) structures on Ni foam via a facile, cost-effective, two-step hydrothermal route. The as-grown 3D architecture exhibited excellent areal capacitance of 4.33 F cm^(-2)at a galvanostatic chargedischarge current density of 50 mA cm^(-2)(6 Ag^(-1)) and outstanding cycle performance with only 2.8%degradation over 6500 cycles in the 3 M KOH solution. The asymmetric all-solid-state supercapacitors based on activated carbon(AC) and CMCMs exhibited much better electrochemical performance than the symmetric counterpart, showing an areal capacitance of 95.22 mF cm^(-2)at the current density of 12 m A cm^(-2)and excellent cycling stability with 92.27% of the initial capacitance after 5000 cycles. These results may provide useful guidelines for materials selection and configuration designs for the novel energy storage devices based on Co Mo O4 components and substrates.Xuewen Geng Yuanfei Ai Guozhen Shen 2016Progress in Natural Science:Materials International2016,26,3:0
2Direct growth of Fe_3O_4-MoO_2 hybrid nanofilm anode with enhanced electrochemical performance in neutral aqueous electrolyte显示文摘To enhance the electrochemical energy storage performance of supercapacitors(SCs), the current researches are general directed towards the cathode materials. However, the anode materials are relatively less studied. In the present work, Fe_3O_4-MoO_2(FO-MO) hybrid nano thin film directly grown on Ti substrate is investigated, which is used as high-performance anode material for SCs in Li_2SO_4 electrolyte with the comparison to pristine Fe_3O_4 nanorod array. The areal capacitance of FO-MO hybrid electrode was initially found to be 65.0 m F cm^(-2)at 2 m Vs^(-1)and continuously increased to 260.0% after 50 cycles of activation. The capacitance values were considerably comparable or higher than many reported thinfilm iron oxide-based anodes in neutral electrolyte. With the protection of MoO_2 shell, the FO-MO electrode developed in this study also exhibited excellent cyclic stability(increased to 230.8% after 1000cycles). This work presents a promising way to improve the electrochemical performance of iron oxidebased anodes for SCs.Ruizhi Li Xin Ba Yimeng Wang Wenhua Zuo Chong Wang Yuanyuan Li Jinping Liu 2016Progress in Natural Science:Materials International2016,26,3:0
