This review provides a comprehensive comparison of mainstream spinning techniques—including melt spinning,solution spinning,and electrospinning—evaluating their respective advantages and limitations,with a specific focus on their regulatory effects on the morphology and structure of the as-spun fibers.This analysis is central to understanding the fundamental relationships between processing conditions and the resulting electrochemical and mechanical properties of lignin-derived carbon fibers (LCFs).Furthermore,the article elaborates on the innovative applications and performance of LCFs in various advanced energy storage systems,such as supercapacitors,lithium/sodium/zinc-ion batteries,and lithium-sulfur batteries,thereby demonstrating their significant potential as high-performance electrode materials or functional components.The overarching aim of this work is to provide a theoretical foundation and technical insights to guide the rational design of LCFs and to foster their synergistic integration with sustainable energy storage technologies.
