Hierarchical Ni(OH)2@CoMoO4 nanoflake composite on Ni foam was successfully constructed by electrodepositing Ni(OH)2 onto CoMoO4 nanoflake and investigated as binder-free electrodes for supercapacitor. The composite shows a large areal capacitance of 5.23[Formula: see text]F[Formula: see text]cm[Formula: see text] at current density of 8[Formula: see text]mA[Formula: see text]cm[Formula: see text], and a capacitance retention of 82.5% after 1000 cycles. The high electrochemical performances can be attributed to the hierarchical nanoflakes structure and the synergetic effect between Ni(OH)2 nanosheets and CoMoO4 nanoflakes. This work demonstrates that Ni(OH)2@CoMoO4 nanoflake composite is highly desirable for application as advanced electrochemical electrode material.

Adsorption Desorption

A facile route has been employed to synthesize a series of high performance activated carbons as the electrode material for supercapacitors. The structure of the carbons are characterized by N2 adsorption/desorption and FTIR spectroscopy. The electrochemical performances of the carbons as an electrode material were evaluated by cyclic voltammetry test and galvanostatic charge/discharge measurements. As a biomass derived carbon, KOH-1 exhibits high capacity, good rate capability and high energy density, indicating the promising application of hydrothermal combining with KOH activation method for biomass materials that used in supercapacitors
