Regulating Closed Pore Structure of Coal-Based Hard Carbon Anode by Preoxidation for High-Rate Performance Sodium-Ion Batteries

Langmuir, Год журнала: 2025, Номер unknown

Опубликована: Фев. 7, 2025

Coal-derived hard carbons (CHCs) have considerable potential as sodium storage materials because of their abundant resources and structural diversity. Nevertheless, the smaller layer spacing ordered carbon microstructure CHCs bring about low charge/discharge rates poor cycle life sodium-ion batteries (SIBs), rendering it challenging to support large-scale energy applications. Herein, preoxidation strategy is employed achieve multiscale structure optimization improve its capacity. The oxygen content in preoxidized coal reached 15.2%, contributing increasing cross-linked materials. Particularly, insertion Na+ facilitated by large 0.394 nm, well closed pores (0.162 cm3 g-1) improving diffusion Na+. Consequently, rate performance as-optimized anode (OCHC3) superior that directly carbonized. Specifically, OCHC3 exhibits a commendable (201 mAh achieves outstanding cycling stability (96.2%) over 500 cycles. Furthermore, galvanostatic intermittent titration reveals "adsorption-insertion-filling" OCHC3. This study enlightens rational design high-performance HC anodes for SIBs beyond.
