Abstract Sodium‐ion batteries (SIBs) emerge as a sustainable and cost‐effective alternative to lithium‐ion due the abundant widely distributed nature of sodium resources. Hard carbon anodes, characterized by their pseudo‐graphitic layered structures nanoporosity, are key achieving high‐performance SIBs. However, commercialization hard is hindered significant challenges in precursor design, carbonization optimization, sustainability. This review focuses on critical role selection introduces classification system based volatile content. High‐volatility biomass precursors, such bamboo, require pretreatments like acid/alkali leaching or hydrothermal processing optimize pyrolysis. Medium‐volatility resins plastics benefit from crosslinking strategies, while low‐volatility materials biochar petroleum coke rely nanochannel engineering improve storage performance. Bamboo‐based precursors highlighted promising pathway renewability environmental advantages, though impurity control structural persist. By integrating design with this provides comprehensive framework for understanding microstructural regulation performance enhancement. The insights presented offer valuable guidance developing scalable approaches produce materials, paving way next generation SIB technologies.

Abstract The pursuit of advanced anode materials to address inferior conductivity and slow ion diffusion has driven the development fast‐charging sodium‐ion batteries (SIBs). Herein, a promising material KCu 7 S 4 nanowires with tunnel structure is proposed for SIBs. Na + (de)insertion mechanisms are comprehensively elucidated through combination in situ TEM/SAED/XRD analyses theoretical calculations. detailed intermediates (Na 3 Cu , NaCuS) final products (CuS, Cu) during (de)sodiation processes identified, revealing that highly mobile can facilitate formation tunnel‐structured layer‐structured NaCuS electrochemical reaction process. dynamics indicate facilitates electron transfer (de)insertion. Moreover, exhibits high discharge capacity 337 mAh g −1 at 10 A corresponding V 2 (PO ) //KCu full cell delivers energy density 303 Wh kg 375 W demonstrating its excellent application prospect. This work opens new avenue electrode
