Abstract:

Lignin is an aromatic polymer with abundant reserves on Earth. It is rich in hydroxyl, carboxyl, ether, and other functional groups. The presence of these functional groups allows the selective modification of this complex compound. Lignin is a by-product of the pulp and paper industry, which is inexpensive and has a wide range of sources. The porous lignin-based carbon prepared by a simple and mild chemical activation has become a research hotspot in the fields of environmental purification, electrocatalysis, and energy storage, especially as an anode material for lithium-ion batteries. This review briefly introduces the energy storage mechanism and the characteristics of lithium-ion batteries and summarizes the mechanism, preparation methods, and research status of lignin in the anode materials of lithium-ion batteries. The anode materials are divided into lignin-based layered porous carbon, carbon microsphere, carbon fiber, carbon nanotube, and other composites. The application of lignin to a lithium-sulfur battery is also investigated. Finally, the existing problems faced by lignin used as the electrode materials for lithium-ion batteries are put forward, and future work is prospected.

Key words: lignin, lithium-ion battery, anode material, battery separator, adhesive, cathode additive
