“…These advantages render biomass as promising precursors for high‐performance hard carbon anodes after certain treatments, which have attracted more and more research efforts. [ 118–124 ] Biomass is of high diversity in regard to composition, morphology, and nanostructure. The electrochemical performances of biomass‐derived hard carbon anodes in LIBs vary significantly due to different kinds of precursors and different preparation processes.…”

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.

“…Many researchers have demonstrated that macropores can provide transportation channels for lithium ion diffusion, micropores can act as reservoirs to improve the capacity of lithium ion storage, and mesopores offer highways for lithium ion transportation. ,,− The values for S BET , the average pore size, and the pore volume of N,P@C were calculated to 675.4 m 2 /g, 6.898 nm, and 2.383 cm 3 /g, respectively. In comparison with most of the biomass-derived anode materials in the literature, N,P@C shows higher S BET value, which is associated with the synthesis procedure of the carbon material. ,, Both the high S BET value and the hierarchical pore structure benefit the efficient electrochemical performance of lithium ion battery by exposing more active sites and facilitating lithium ion diffusion. , …”

Biomass-derived heteroatom-doped carbons have been considered to be excellent lithium ion battery (LIB) anode materials. Herein, ultrathin g-C 3 N 4 nanosheets anchored on N,P-codoped biomass-derived carbon (N,P@C) were successfully fabricated by carbonization in an argon atmosphere. The structural characteristics of the resultant N,P@C were elucidated by SEM, TEM, FTIR, XRD, XPS, Raman, and BET surface area measurements. The results show that N,P@C has a high specific surface area ( S BET = 675.4 cm 3 /g), a mesoporous-dominant pore (average pore size of 6.898 nm), and a high level of defects ( I D / I G = 1.02). The hierarchical porous structural properties are responsible for the efficient electrochemical performance of N,P@C as an anode material, which exhibits an outstanding reversible specific capacity of 1264.3 mAh/g at 100 mA/g, an elegant rate capability of 261 mAh/g at 10 A, and a satisfactory cycling stability of 1463.8 mAh/g at 1 A after 500 cycles. Because of the special structure and synergistic contributions from N and P heteroatoms, the resultant N,P@C endows LIBs with electrochemical performance superior to those of most of carbon-based anode materials derived from biomass in the literature. The findings in this present work pave a novel avenue toward lignin volarization to produce anode material for use in high-performance LIBs.
