Abstract Silicon/carbon (Si/C) composites present great potential as anode materials for rechargeable batteries since the integrate high specific capacity and preferable cycling stability from Si C components, respectively. Functional Si/C based on lignocellulose have attracted wide attention due to advantages lignocellulose, including sustainability property, flexible structural tunability, diverse physicochemical functionality. Although flourishing development of boosts studies lignocellulose‐derived with electrochemical performance, publications that comprehensively clarify design functionalization these high‐profile are still scarce. Accordingly, this review first systematically summarizes recent advances in after a brief clarification about selection sources self extraneous sources. Afterward, strategies, nanosizing, porosification, magnesiothermic reduction material well heteroatom modification material, specifically highlighted. Besides, applications Si/C‐based elaborated. Finally, discusses challenges prospects application energy storage provides nuanced viewpoint regarding topic.

Abstract Silicon (Si)‐based anodes hold great potential for next‐generation lithium‐ion batteries (LIBs) due to their exceptional theoretical capacity. However, practical application is hindered by the notably substantial volume expansion and unstable electrode/electrolyte interfaces during cycling, leading rapid capacity degradation. To address these challenges, we have engineered a porous nitrogen/sulfur co‐doped carbon layer (CBPOD) uniformly encapsulate Si, providing multifunctional protective coating. This innovative design effectively passivates interface mitigates volumetric of Si. The N/S co‐doping framework significantly enhances electronic ionic conductivity. Furthermore, carbonization process augments elastic modulus CBPOD reconstructs Si‐CBPOD interface, facilitating formation robust chemical bonds. These features collectively contribute high performance anodes, which demonstrate reversible 1110.8 mAh g −1 after 1000 cycles at 4 A an energy density 574 Wh kg with retention over 75.6% 300 0.2 C. study underscores in enhancing Si pathway development composite materials superior prolonged cyclic stability, thereby advancing high‐performance LIBs.

Lithium-ion batteries (LIBs) with silicon/graphite composite (Si/C) anodes are still facing the challenge of unsatisfactory calendar life, and specific impact Si on this issue is largely unknown. Herein, aging behaviors quantified across scales explored in a top-down manner. Batteries 10 wt % Si/C suffer 4-fold decrease overall lifetime 4–5-fold increase irreversible anode loss. Significant parasitic reactions solid electrolyte interphase growth occur after 72 h storage an oxygen 1.3 times surface 26 interphase. The micromorphology component analyzed detail, highlighting remarkable Li2CO3 precipitation. Finally, discussed both external conditions internal components. Mitigating decomposition caused by active will be key to improving battery's life.

Due to its many benefits, including high specific capacity, low voltage plateau, and plentiful supplies, silicon-based anode materials are a strong contender replace graphite anodes. However, silicon has drawbacks such as poor electrical conductivity, abrupt volume changes during the discharge process, continuous growth of solid electrolyte interfacial (SEI) film cycling, which would cause electrode capacity degrade quickly. Coating silicon's exterior with carbon or metal oxide is popular method resolve above-mentioned problems. In light those above, liquid-phase approach electrostatic spinning technique were used in this work create Si@MnO@CNFs bilayer-coated materials. Because well-thought-out design, MnO C bilaterally coat nanoparticles, significantly reducing their effect cycling. Furthermore, manganese outstanding electrochemical kinetics an excellent theoretical capacity. The nanofibers' outermost layer increases material's conductivity stabilizes composite structure, effect. After 1100 cycles at 2 A g-1, material prepared can still maintain 994.4 mAh g-1. This study offers unusual combination that might set way for application composites lithium-ion batteries.
