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.

Due to its unique structure and high capacity, bamboo-based hard carbon is often regarded as the most promising anode material for sodium-ion batteries. However, low sodium storage ability poor Na+ transportation limit development of bamboo-derived carbon. In this study, bamboo powder (BP) was pretreated with acidic potassium permanganate, in which strong oxidizing properties introduced more oxygen-containing functional groups into skeleton. addition, two-step carbonization process facilitated formation hierarchical pore structures (BP-A-P). Electrochemical measurements demonstrated that BP-A-P exhibited superior activity stability. Under current multiplication 0.1 C, a reversible specific capacity 338 mAh/g achieved first Coulombic efficiency 81.7%. The excellent performance mainly attributed rich micropores abundant closed pores, are induced by permanganate. Moreover, exhibits stability maintained at 273 after 100 cycles. Thus, permanganate treatment provides new strategy achieving complex pores high-performance

Abstract Pre‐oxidation treatment is a key process in producing pitch‐derived hard carbon for sodium‐ion battery anodes, however, the oxidative crosslinking mechanism of pitch remains elusive. This study aims to delve into influence softening points pitches and pre‐oxidation durations on variability oxidation behavior. The results demonstrate that due interconnection polycyclic aromatic hydrocarbons presence methyl groups are directly attached rings. These structural features make with higher more susceptible regardless reaction period. Specifically, they transformed branched structures via ring‐opening, increasing likelihood oxidation. Further reactions generate functional such as esters carboxylic acids, promoting pitch, thus converting from soft carbon, reversible capacity 105.1 259.6 mAh g −1 . However, low point featured by hydrocarbon linkage failed be pre‐oxidized. this research provide profound comprehension mechanisms which guide design transform improving processes obtaining high performance batteries.
