Ni-Al-Pr LDH and Ni-Al-Pr LDH/reduced graphene oxide (rGO) electrode materials were prepared by hydrothermal synthesis method.The composition,structural and morphology of the samples were characterized using X-ray diffraction (XRD),fourier transform infrared spectrum (FT-IR),and scanning electron microscope (SEM).Meanwhile,the effect of rGO adding amount on electrochemical performance of Ni-Al-Pr LDH was investigated.The results shown that the composite materials containing 4% rGO exhibited higher electrochemical performance,with a specific capacitance of 1101F/g at a current density of 1A/g.The electrochemical performance of the composite materials was far superior to those of Ni-Al-Pr LDH with a specific capacitance of 439F/g.This indicated that the combination of rGO could improve the electrochemical performance for electrode materials to a certain extent.
