Abstract： Using nickel nitrate and manganese chloride as the main raw materials， nickel-manganese bimetallic oxide （Ni-MnO4） ） was grown on carbon fiber （CF） via the hydrothermal method. The effects of different molar ratios of Ni and Mn on the morphology， structure， and electrochemical properties of Ni-MnO4/CF were investigated. The structure，morphology， and electrochemical properties of the composite materials were characterized using X-ray diffractometer （XRD）， scanning electron microscope （SEM），and an electrochemical workstation. The results indicate that adjusting the molar ratio of ΔNi and Mn， the morphology of the composite material can be well regulated and its electrochemical properties can be changed. With the increase of Ni element， the morphology of NiMnO4/CF gradually transforms from the stacked bud-like to thin sheet-like. When n（Ni）：n（Mn）=2：1 Ni-MnO4/CF exhibits relatively favorable electrochemical properties. When the current density increased from 1A/g to 5A/g ， the specific capacitance of Ni-MnO4/CF decreased from 1669F/g to 1015F/g ， and the specific capacitance retention rate is 60.8% ：
