摘要
The Ni3S2/Ni(OH)(2) electrode could deliver a high areal capacity of 1.58 C/cm(2) at 2 mA/cm(2), along with outstanding cycling stability (113% capacity retention after 30,000 cycles). The energy density of the Ni3S2/Ni(OH)(2)//AC hybrid device was 30.23 Wh/kg at a power density of 155 W/kg (15.5 Wh/kg at 3,875 W/kg). Compared with other Ni(OH)(2) composites on Ni foam, these results indicate that Ni3S2/Ni(OH)(2) directly grown on Ni foam opens up the potential application for energy storage devices with high areal capacity and high cycling performance.
