Abstract:

Based on the advantages of low cost, renewability, abundant sources, simple preparation process and controllable structure of lignin natural polymer, it has been used to prepare carbon fiber and applied to energy storage components such as supercapacitors and rechargeable batteries. The advantages of fast charge and discharge speed, high energy density and long cycle life have been confirmed and applied. The process technology and fiber properties of lignin-based carbon fibers prepared by spinning method in recent years were systematically reviewed. Based on the structural design diversity of lignin-based carbon fibers, the different electrochemical properties of different lignin-based carbon fibers as electrode materials for supercapacitors and rechargeable batteries were summarized. In addition, an overview of the development prospects and challenges of lignin-based carbon fiber composites was provided to think for the next step of research and development of lignin-based carbon fiber composites.

Key words: lignin, carbon fiber, supercapacitors, lithium-ion batteries, sodium-ion batteries
