Abstract Polyanion compounds arouse significant interest as cathode materials for sodium‐ion batteries due to their large 3D lattice structures and stable frameworks. Nonetheless, it remains a great challenge polyanion cathodes achieve both considerable rate capability long‐term cycling lifespan. Herein, high entropy NASICON‐type cathode, Na 3.6 VMn 0.4 Fe Ti 0.1 Zr (PO 4 ) 3 (HE‐NVMFTZP), is successfully synthesized the first time exhibits superior sodium storage performance. Specifically, delivers reversible capacity of 110 mAh g −1 , remarkable (78.5 even at 20 C), an ultralong lifespan (80.6% after 10 000 cycles which outperforms all reported metal‐substituted NASICON electrodes. Moreover, in expanded voltage window 1.5–4.3 V, HE‐NVMFTZP electrode impressive 177.4 (≈494 Wh kg ). Comprehensive experimental characterizations first‐principles calculations reveal that effect facilitates ion/electron transportation alleviates volume expansion phase transition during charge/discharge process. This work provides facile strategy on local structural engineering effectively boost performance can shed light design high‐capacity materials.

ABSTRACT Sodium‐layered oxides are a promising category of cathodes for sodium‐ion batteries with high energy densities. The solid‐state method is the typical approach to synthesizing these because its simple procedure and low cost. Although reaction conditions have usually been understated, effect reagents has often overlooked. Thus, fundamental insight into chemical required perform well. Here we report in situ structural electrochemical methods studying using different reagents. materials composite structure containing layered NaMnO 2 Li MnO 3 components, where oxygen anionic redox can be triggered at voltage by forming Na–O–Li configurations. samples synthesized via MnCO ‐based precursors form phase evaluated temperature better than those through precursors. This work demonstrates that also impact performance sodium‐layered oxides, which provides new developing high‐energy cathode material.
