摘　　要：采用化学活化法,将浸泡在饱和氯化钾溶液中12 h的蚕丝烘干并置于含有少量还原性气体(5%H 2)的氮气气氛中,分别在600℃、700℃高温碳化合成样品,并将其制备成超级电容器负极。采用X射线衍射仪,扫描电子显微镜等表征所合成样品的微观形貌结构,采用电化学工作站等研究其作为电极材料的电化学储能性能。结果表明,700℃碳化样品在0.1 A/g的电流密度下电极比容量可达到205.4 F/g,具有较好的电化学性能。研究结果有望为生物质温和活化开发及储能应用提供新思路。Using the chemical activation method,the silk soaked in saturated potassium chloride solution for 12 hours was dried and placed in a nitrogen atmosphere containing a small amount of reducing gas(5%H 2)and carbonized at 600℃and 700℃respectively to prepare the negative electrode of supercapacitor.X-ray diffraction and scanning electron microscopy were used to characterize the microstructure of the synthesized samples,and their electrochemical energy storage performance as electrode materials was studied.The results show that the specific capacity of the 700℃electrode reaches 205.4 F/g at a current density of 0.1 A/g.It has better electrochemical performance,which is expected to provide new ideas for the development of biomass mild activation and energy storage applications.
