基于同轴湿法纺Co3O4系列纤维超级电容器的制备及研究
Preparation andStudy of Co3O4-based Fiber Supercapacitors via Coaxial Wet Spinning Method
摘要
Abstract
The rapid development of intelligent wearable electronic devices is gradually transforming people's lifestyles.In this wave of technological innovation,the demand for flexible energy storage devices is becoming increasingly prominent.Among these,fiber supercapacitors are considered one of the most promising wearable energy storage systems.Compared with traditional energy storage devices,fiber-based supercapacitors offer sig-nificant advantages such as small size,light weight and high flexibility,making them ideal for portable energy supply systems.In this paper,coaxial wet spinning technology was used to prepare nanoscale Co3O4,nanoscale Co3O4/CNTs,nanoscale Co3O4/MXene fiber electrode filaments and a series of symmetric supercapacitors.The systematic electrochemical performance tests were conducted to analyze and compare electrochemical factors.The results showed that the nanoscale Co3O4,nanoscale Co3O4/CNTs,and nanoscale Co3O4/MXene series of fiber supercapacitors all exhibited pseudocapacitive energy storage mechanism,demonstrating excellent reversibility and rate performance.Among these,the nanoscale Co3O4 fiber supercapacitor had the highest specific capaci-tance value at 0.45 μF/cm and the highest energy density at 2.35×10-5 μWh/cm,and the nanoscale Co3O4/Mxene fiber supercapacitor had the highest power density at 1.18 μWh/cm.关键词
