摘要: 为满足柔性超级电容器对高性能电极材料的迫切需求，本研究采用电沉积法在亲水碳布(HCC)上原位生长镍钴层状双氢氧化物(NiCo-LDH)，系统探究了沉积时间(1000 s、1500 s、2000 s)对复合材料形貌、晶体结构及电化学性能的影响。通过扫描电镜(SEM)、X射线衍射(XRD)和X射线光电子能谱(XPS)等表征手段证实，1500 s沉积条件下所得材料具有均匀的纳米片层结构、较高的结晶度以及良好的Ni2+/Ni3+与Co2+/Co3+氧化还原活性。电化学测试表明，该材料在1 A/g电流密度下比电容高达1588 F/g，经过3000次循环后，电容保持率达74.7%，展现出优异的循环稳定性与快速的电荷传输动力学。本研究验证了电沉积法在温和条件下构筑结构可控、性能突出的柔性电极材料的可行性，为高性能超级电容器的设计与开发提供了重要参考。
Abstract: To address the urgent demand for high-performance electrode materials in flexible supercapacitors, this study employed an electrodeposition method to in situ grow nickel-cobalt layered double hydroxide (NiCo-LDH) on hydrophilic carbon cloth (HCC). The effects of deposition time (1000 s, 1500 s, 2000 s) on the morphology, crystal structure, and electrochemical performance of the composite material were systematically investigated. Characterization via scanning electron microscopy (SEM), X-ray diffraction (XRD), and X-ray photoelectron spectroscopy (XPS) confirmed that the material synthesized under 1500 s deposition conditions exhibits a uniform nanolayer structure, high crystallinity, and excellent Ni2+/Ni3+ and Co2+/Co3+ redox activity. Electrochemical testing revealed a specific capacitance of 1588 F/g at a current density of 1 A/g. After 3000 cycles, the capacitance retention reached 74.7%, demonstrating excellent cycling stability and fast charge transfer kinetics. This study validates the feasibility of using electrodeposition to construct structurally controllable, high-performance flexible electrode materials under mild conditions, providing important reference for the design and development of high-performance supercapacitors.
