Abstract:

Lignin is a kind of abundant, inexpensive, and renewable biological resource, which has been widely used in the industrial field. Lignin has made some progress, but its application in energy storage is very limited. The research progress of lignin and its derivatives in rechargeable batteries (i.e., lead acid and lithium-ion batteries), fuel and cells, and supercapacitors is reviewed herein to broaden its application scope in energy storage materials. Among them, the basic properties and characteristics of lignin from different sources are briefly introduced, and based on the design flexibility and diversity of lignin and its derivatives in molecular structure, additives, binders, catalysts, battery or supercapacitor electrode materials are prepared by directly selecting lignin or modifying or doping one or more heteroatoms. Moreover, the operation mechanism and electrochemical performance of different lignin-based energy storage devices are discussed and analyzed. The results show that lignin application in the energy storage device not only improves the cycle stability and extends the service life, but also reduces production costs and chemical pollution. The challenges and the possible development directions of lignin-based energy storage materials in the future are prospected herein to further improve the energy storage and output efficiency of lignin-based energy storage devices.

Key words: lignin, storage energy, battery, supercapitor, electrochemical performance
