ABSTRACT: Lignin, a natural polymer material, has demonstrated significant potential for
advancement in the field of electrochemical energy storage. The utilization of lignin-derived
functional materials has greatly improved the performance and durability of devices for
electrochemical energy storage while simultaneously mitigating environmental pollution. The
present thesis investigates the application of lignin-derived electrochemical functional
materials, including electrode materials, electrolytes, conductive agents, and binders. When
employed as electrodes, lignin-derived carbon materials exhibit remarkable modifiability
(doping, cross-linking, and composite). Importantly, the presence of heteroatoms and active
sites for cross-linking plays a crucial role in regulating the disorder within the carbon layer and
controlling pore parameters. Lignin-based polymer materials, when employed in non-
electrochemically active storage functional components such as electrolytes, separators, and
binders, demonstrate exceptional mechanical strength, superior adhesion properties, and
enhanced ionic conductivity due to their distinctive phenylpropane structure and functional
groups (hydroxyl, carboxyl, and carbonyl). Additionally, we conducted a comprehensive analysis of the current market prospects for
lignin in supercapacitors and lithium-/sodium-ion batteries. Furthermore, we have systematically examined the challenges and
opportunities that lignin encounters in the field of energy storage, thereby providing valuable insights for further advancements in
lignin-based electrochemical energy storage materials.
