Lignocellulosic biomass-derived pyrolysis hard carbon (LCB-HC) shows promising commercial potential as an anode material for sodium-ion batteries (SIBs). LCB compromises multiple biopolymer sources, including cellulose, hemicellulose, and lignin, which influence the formation microstructure of HC. However, poor plateau kinetics LCB-HC is one main obstacles that severely limits its energy density with high power density, could be attributed to narrow interlayer distance lack abundant closed pores intercalation/filling Na+. Herein, we proposed a bottom-up approach tailoring by regulating components precursor at molecular level using bioenzymes secreted lignocellulolytic bacteria. This mild efficient enzymatic hydrolysis pathway partially depolymerized biopolymers basswood specifically, thereby enabling construction small curved-graphite domain architecture increased enlarged LCB-HC, benefiting low-voltage Na+ storage accelerated kinetics. As result, basswood-derived HC delivers reversible capacity 366.4 mAh g–1 performed remarkable retainability proportion 74.3% even current 1000 mA g–1. Such microbial-chemistry-assisted provided insights into construct high-performance SIB materials.

Abstract Pitch is a highly preferable and cost‐effective precursor of carbon materials. Nevertheless, its direct pyrolysis typically yields graphitized soft carbon, posing challenges to the modulation closed‐pore architecture, due intense intermolecular π–π interactions. This results in negligible plateau capacity sluggish diffusion kinetics sodium‐ion batteries (SIBs). In this study, an innovative hyper‐crosslinking strategy proposed reconstruct pitch molecularly precisely tailor structure derived carbon. The crosslinker intertwined units, transforming linear molecules into 3D porous polymers. Structurally, these cavities tactfully reserved space for forming cores, with single‐layer network skeleton ultrathin pore walls upon carbonization. enabled disruption interactions and, therefore, inhibited structural ordering, facilitating transition from graphitic highly‐disordered abundant closed pores featuring appropriate sizes (2 nm) (1–2 layers). optimal sample delivered high 370 mAh g −1 at 30 mA , as well rate capability that surpassed those most previously reported pitch‐derived carbons. Hyper‐crosslinking has advanced development low‐cost high‐performance materials large‐scale energy storage.

Amorphous carbon, particularly hard carbon (HC), is widely considered as the most promising anode material for sodium-ion batteries (SIBs) due to its high reversible capacity and cost-effectiveness. However, complex poorly defined structural properties of HC present challenges in understanding underlying sodium storage mechanisms. To facilitate rational design high-performance anodes, a comprehensive correlation between microstructure behavior critical. This Review critically examines interplay features capabilities, focusing on two key factors: pore structure surface functional groups. It begins by outlining fundamental mechanisms HC, followed an in-depth discussion how chemistry influence storage. Finally, strategic insights are provided manipulate these factors optimize performance. aims drive development next-generation anodes support commercialization SIBs.

Abstract The sluggish charging and restricted mass transfer of cobalt‐based sulfides have provoked in cycling stability, poor rate, low initial coulombic efficiency, impeding their practical application. Developing electronic configurations heterostructures are effective methods to improve conductivity accelerate transfer. In this work, heterostructured carbon/cobalt embedded honeycomb‐like nitrogen‐doped carbon (HC@CoS 2 /CoS/NC) were proposed as a cost‐effective strategy. These composites feature interconnected channels, facilitating rapid electron transport efficient electrolyte diffusion. This self‐induced internal electric field design HC@CoS₂/CoS/NC enhanced the charge movement, inherent optimized electrochemical kinetics anode materials. Theoretical calculations indicate that development with fields is crucial for improving particle/electron movement during charge–discharge cycles sodium‐ion batteries (SIBs), leading Na + demonstrated high specific capacity 809.0 mAh g −1 at 0.1 A , retaining 465.2 after 700 15 .
