It is also the second most abundant natural polymer in nature. In the process of pulp and paper production, a large amount of technical lignin by-products was produced, which was usually utilized as fuel, only a small portion used for other applications. However, advantages of lignin such as natural, environmentally friendly, sustainable renewable and low-cost will be the important niche for development of new materials. If the use of advanced nanotechnology to develop other forms of advanced materials and new applications will increase its use and a substantial increase in added value. This project will use technical lignin as raw material, and adopt electrospinning technology and high-temperature carbonization and activation procedure, making small average diameter, large surface area and large porosity lignin activated carbon nanofiber, and applied to the field of electrochemistry to develop supercapacitors. In addition, the effects of various processes conditions on the properties of the fibers and on the final supercapacitor products will also be explored. A supercapacitor of excellent charge and discharge performance will be produced in this project, and that will be able to serve as the basis for the development of green and environment-friendly next generation electronic products. Consequently, this project will be the pioneer for the future development of the domestic natural fiber nanomaterials with high value utilization, and in addition to contribute to the sustainable development of environmental protection, this project will also contribute to domestic biomaterials science research and green energy related applications.木質素靜電紡絲超級電容器lignin，electrospinningsupercapacitor
