Pyridinic N‐Dominated Hard Carbon with Accessible Carbonyl Groups Enabling 98% Initial Coulombic Efficiency for Sodium‐Ion Batteries

Advanced Functional Materials, Год журнала: 2024, Номер unknown

Опубликована: Июнь 5, 2024

Abstract Hard carbon (HC) has been widely regarded as the most promising anode material for sodium‐ion batteries (SIBs) due to its decent capacity and low cost. However, poor initial Coulombic efficiency (ICE) of HC seriously hinders practical application in SIBs. Herein, pyridinic N‐doped hard polyhedra with easily accessible carbonyl groups situ coupled nanotubes are rationally synthesized via a facile pretreated zeolitic imidazolate framework (ZIFs)‐carbonization strategy. The comprehensive ex/in techniques combined theoretical calculations reveal that synergy pyridinic‐N promoted by pretreatment carbonization process would not only optimize Na + adsorption energy but also accelerate desorption , significantly suppressing irreversible loss. As result, as‐synthesized an can deliver unprecedented high ICE 98% large reversible 389.4 mAh g −1 at 0.03 A . This work may provide effective strategy structural design ICE.
