| 英文摘要 |
A three-dimensional (3D) conductive network as the current collector is
critical to enabling high-performance power sources because it not only provides a
highly electrolytic accessible area of electroactive materials, but also facilitates
electron and electrolyte ion transport. Here, we design a facile method to construct
a secondary porous Ni structure (SPNi) on the surface of Ni foam. The SPNi-Ni
scaffold can increase the loading of active materials and facilitate transportation
of electrons and electrolyte ions. As a demonstration, after depositing Co(OH)(2)
active material, it can deliver much higher area-specific capacitance of 11.91 F/cm
(2) at a current density of 10 mA cm(-2) and cyclic stability (similar to 16% loss
after 1000 cycles) than those on the bare Ni foam under the identical current
density (3.57 F cm(-2), 30% loss after 1000 cycles). The results establish that the
bicontinuously 3D porous scaffold is a promising candidate for building up high
performance energy storage devices. |
