摘要：
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 F cm(-2) at current density of 8 mA cm(-1), 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.
