“…In addition to cellulose, lignin, as the second abundant biomass polymer, is provided with high carbon yield (>50 wt%) and low cost for preparing hard carbons. [ 145–149 ] Lignin is mainly composed of three kinds of aromatic structural units including p‐hydroxyphenyl, guaiacyl, and syringyl. The types of plants determine the ratio of p‐hydroxyphenyl, guaiacyl, and syringyl.…”

Carbonaceous materials have been accepted as a promising family of anode materials for lithium‐ion batteries (LIBs) owing to optimal overall performance. Among various emerging carbonaceous anode materials, hard carbons have recently gained significant attention for high‐energy LIBs. The most attractive features of hard carbons are the enriched microcrystalline structure, which not only benefits the uptake of more Li+ ions but also facilitates the Li+ ions intercalation and deintercalation. However, the booming application of hard carbons is significantly slowed by the low initial Coulombic efficiency, large initial irreversible capacity, and voltage hysteresis. Many efforts have been devoted to address these challenges toward practical applications. This paper focuses on an up‐to‐date overview of hard carbons, with an emphasis on the lithium storage fundamentals and material classification of hard carbons as well as present challenges and potential solutions. The future prospects and perspectives on hard carbons to enable practical application in next‐generation batteries are also highlighted.

The utilization of binders has severely hindered ionic diffusion and electron transfer in the traditional lithium-ion battery. Herein, a self-standing hard carbon film using nanocellulose as precursor has been constructed as binder-free electrodes via two-step thermal treatment. The cyclization and aromatization of small molecular fragments promote the formation of hyper-crosslinked framework with abundant welded junctions. Importantly, carbon nanofibers not only serve as an inter-connected conductive network for fast electron transfer, but also as an interlinked mechanical skeleton for convenient Li + diffusion and electrode structural stability. Furthermore, the optimized carbon film, with accessible redox-active carbonyl groups (C O) and abundant micropores, is beneficial for Li + accommodation. It exhibits high reversible capacity of 513.1 mAh g −1 at 50 mA g −1 and excellent cycle stability to extend over 1000 cycles without signs of decay. This study provides an efficient strategy for the design of high-performance biomass-derived anode materials with stablestructure for alkaline batteries.

“…The aromatic components of sodium lignin sulfonate promote a great yield of graphitic segments, which is generally associated with superior conductivity [87]. A hard carbon microsphere (HCM) is created using simple spray drying and carbonization (Figure 6b) [88]. HCM achieves an interlayer distance of 0.396 nm, an initial capacity of 339 mAh g −1 , and capacity retention of 93% after 100 cycles in NIB.…”

“…The HCM is dense, resulting in fewer surface defects, a smaller surface area, and a lower SEI production rate. Furthermore, the increased interlayer spacing and organized graphitic nano-domain facilitate reversibility [88]. Lignin-derived hard carbons were also applied in a K-ion battery, which is another promising next-generation battery system based on the high energy density and low cost [89].…”

This review discusses important scientific progress, problems, and prospects of lignin-based materials in the field of rechargeable batteries. Lignin, a component of the secondary cell wall, is considered a promising source of biomass. Compared to cellulose, which is the most extensively studied biomass material, lignin has a competitive price and a variety of functional groups leading to broad utilization such as adhesive, emulsifier, pesticides, polymer composite, carbon precursor, etc. The lignin-based materials can also be applied to various components in rechargeable batteries such as the binder, separator, electrolyte, anode, and cathode. This review describes how lignin-based materials are adopted in these five components with specific examples and explains why lignin is attractive in each case. The electrochemical behaviors including charge–discharge profiles, cyclability, and rate performance are discussed between lignin-based materials and materials without lignin. Finally, current limitations and future prospects are categorized to provide design guidelines for advanced lignin-based materials.
