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 Sodium‐ion batteries (SIBs) hold tremendous potential in next‐generation energy storage. However, no SIB has yet achieved simultaneous support for high voltage, rapid charging, and all‐climate adaptability due to electrolyte limitations. This study successfully constructs versatile SIBs using an optimized acetonitrile (AN)‐based electrolyte, which offers excellent high‐voltage tolerance, ionic conductivity, anion‐enriched solvation structure, a wide liquidus temperature range. The engineered solid interphase (SEI) exhibits low resistance exceptional stability, effectively supporting fast temperature‐adaptive operation, long‐term cycling stability. Consequently, this tailored combined with robust SEI, enables hard carbon (HC) anodes achieve reversible capacity of 223 mAh g −1 at rate 5 C. When paired NaNi 1/3 Fe Mn O 2 (NFM) cathode, the HC||NFM full cells operate stably cut‐off voltage 4.15 V, sustaining over 1400 cycles Furthermore, practical 3 Ah pouch cell demonstrates retaining 90.7% its after 1000 cycles, shows adaptability, maintaining 56.4% room‐temperature −60 °C 97.3% retention 350 50 °C. work provides valuable insights developing advanced electrolytes SIBs.

Опубликована: Янв. 5, 2024

Abstract Versatile nitrogen‐centered organic redox‐active molecules have gained significant attention in alkali metal‐ion batteries (AMIBs) due to their low cost, toxicity, and ease of preparation. Specially, multiple reaction categories (anion/cation insertion types reaction) higher operating voltage, when compared traditional conjugated carbonyl materials, underscore promising prospects. However, the high solubility redox active materials electrolyte electronic conductivity contribute inferior cycling performance, sluggish kinetics, limited rate capability. This review provides a detailed overview encompassing chemistry, solutions overcome shortcomings, characterization charge storage mechanisms, recent progress. Additionally, prospects directions are proposed for future investigations. It is anticipated that this will stimulate further exploration underlying mechanisms interface chemistry through situ techniques, thereby promoting practical application AMIBs.
