Insight into the Role of Closed‐Pore Size on Rate Capability of Hard Carbon for Fast‐Charging Sodium‐Ion Batteries

Advanced Materials, Год журнала: 2025, Номер unknown

Опубликована: Апрель 17, 2025

The sluggish Na ion diffusion kinetics and metal plating in hard carbon negative electrodes restrict the fast-charging of sodium-ion batteries, which is intricately entwined with crystal structure pore structure. Here, structures materials are focused on reveal that size significantly affects Na-filling potentials during sodiation process. Specifically, micro closed pores exhibit higher potentials, reduces risks at high current densities, thus enabling improved rate performance. As a result, optimized micropores (1.6 nm) achieves an initial capacity exceeding 400 mAh g-1 20 mA plateau retention 73.3% density 500 g-1. Paired P2-type layered oxide positive electrodes, 2.2 Ah pouch cell shows 10 min charging for ≈90% after 1500 cycles 6C rate. This work establishes bridge between performance, offering guidance design batteries.
