摘要: Abstract In this work, NiO@MnO 2 core/shell nanocomposites were fabricated by a two-step method. The morphology and structure of the characterized scanning electron microscopy, transmission X-ray photoelectron spectroscopy, diffraction analysis thermal gravity analysis. addition, supercapacitive performances examined cyclic voltammogram (CV), galvanostatic charge⿿discharge electrochemical impedance spectroscopy (EIS). results indicate that composite exhibits specific capacitance 266.7 F g ⿿1 at 0.5 A g excellent cycling stability (81.7% retention after 2000 cycles 1 A g ). Therefore, wok offers meaningful reference for supercpacitor applications in future.
