The NiCo2O4 nanosheets uniformly grown on the Ni foam (CF)(NiCo2O4/NF) were successfully fabricated by a hydrothermal method,followed by the calcination process.The compositions,morphologies and electrochemical performance of NiCo2O4/NF were demonstrated by XRD,SEM,N2 adsorption/desorption measurements,and electrochemical measurements.The results suggested that the NiCo2O4 nanosheets uniformly grown on the NF,and NiCo2O4 nanosheets had the good electrochemical performance.For example,the specific capacitance value of NiCo2O4/NF was up to 1102F/g and the after a 4000-cycle test at a current density of 10A/g,the retention capacitance value was about 88.7%.In addition,an ASC was assembled using NiCo2O4/NF as the positive electrode and activated carbon (AC) as the negative electrode,which shown a high energy density and remarkable cycling performance.
