柔性电子器件是未来发展的趋势。柔性器件需要柔性的电源相匹配,而柔性电极材料作为柔性电源的核心,其重要性不言而喻。通过电化学沉积法将金属镍沉积在碳布表面,进而利用溶剂热硫化的方法制备了电化学性能良好的柔性硫化镍电极材料,采用X射线衍射仪、场发射扫描电子显微镜、电化学工作站对材料的结构、形貌和电化学性能进行了表征和分析。结果表明,在电流密度10A/g条件下,经过3000次循环后柔性硫化镍电极材料的比容量仍保持在1620F/g,具有良好的电容性能。
Flexible electronic devices are the trend of future development,and need flexible power sources to match.As the core of flexible power sources,flexible electrode materials are obviously vital.Metallic nickel was deposited on the surface of carbon cloth by electrochemical deposition method,and subsequently,flexible nickel sulfide electrode materials with good electrochemical performance were prepared by solvothermal sulfurization process.The structure,morphology and electrochemical performance were characterized by X-ray diffractometer,field emission scanning electron microscope,and electrochemical workstation,respectively.The results showed that at a current density of 10A/g,the specific capacity of the flexible nickel sulfide electrode material remained at 1620F/g after 3000 cycles,demonstrating good capacitive performance.
