分别应用溶胶凝胶法和室温固相法合成纳米N iO材料,运用DSC、TG等热分析技术分析了合成的样品,通过选择不同的溶剂和调节溶液的pH值,优化溶胶凝胶法合成纳米N iO负极材料.XRD、TEM技术表征材料的结构和形貌,并对所得材料作了电化学性能测试.
The nano-sized NiO materials were synthesized by solid phase method and sol-gel method. The synthesis conditions were optimized by DSC and TG techniques. The sol-gel method was optimized by changing the solvent and regulating the solution's pH for preparing NiO material. The structure and morphology of the materials were also characterized by means of XRD and TEM techniques, and the electrochemical performances of the materials were studied by the galvanostatically charge and discharge experiments.
