摘要：

An electrochemical alternating voltage approach of producing NiCo double hydroxide (NiCoDH) layered ultrathin flakes with with large specific surface area (355.8 m(2) g(-1)), remarkable specific capacitance and rate capability is presented. The obtained NiCoDH as anode for asymmetric supercapacitors shows excellent energy density of 17.5 Wh kg(-1) at high power density of 10.5 kW kg(-1) and cycling stability (91.2% after 10 000 cycles).
