O3-type layered oxides are considered as one of the most promising cathode materials for sodium-ion batteries (SIBs) owing to their high initial sodium content, reversible capacity, mature synthesis process, and low production cost. However, adverse phase transition highly air-sensitive issues result in unsatisfactory cycle life poor processing properties, limiting further commercialization. Herein, we prepare a high-entropy metal oxide modified by TiB2 coating layer, which displays increasing structural stability due increase entropy. The layer prevents direct contact between electrolyte electrode, suppresses unfavorable side reaction with electrolyte. Moreover, induces part boron ions (B2−) doping into oxygen CNMT, expanding ion diffusion channels. Consequently, designed Na0.9Cu0.12Ni0.33Mn0.4Ti0.15O2@TiB2 (CNMT@TB) 1 wt% exhibits significantly improvement cycling (capacity retention 91.58% after 200 cycles at 100 mA g−1 93.90% 250 500 g−1) compared pristine CNMT (63.88% 80.07% g−1). This work provides insightful guidance simultaneously enhancing electrochemical performance batteries.

Abstract Lithium‐ion batteries (LIBs) have dominated the market for a long time. However, scarcity of lithium resources has sparked concerns about future energy storage devices, leading many researchers to turn their attention other such as sodium‐ion (SIBs), potassium‐ion (KIBs), zinc‐ion (ZIBs), and so on. Among them, SIBs attracted widespread from due abundant sodium resources, high safety, excellent low‐temperature performance. Because cathode battery determines density, cycle life, charge/discharge rate, cost, research on cathodes is particularly important. Layered oxide cathodes, with periodic layered structure, good electrical conductivity, two‐dimensional ion transport channels, are regarded most promising materials SIBs. Currently, main issues facing include irreversible phase transitions, air sensitivity, insufficient surface residual alkali, migration dissolution transition metals. The key solving these problems lies in development new generation high‐performance cathodes. Hence, we review current progress various optimizing strategies, finally summarize provide an outlook trends image

Abstract Transition metal layered oxides are regarded as commercially viable cathode materials for sodium ion batteries (SIBs), but the inadequate rate capability and cyclability significantly impede their practical application. Here, a high‐entropy‐based micro‐doping strategy has been proposed to prepare an O3‐type Na 0.9 (NiFeMn) 0.3 (CuMgAlTiSn) 0.02 O 2 (HE‐NFM) cathode, delivering ultrahigh energy density of 442 Wh kg⁻¹ at 0.1 C. The HE‐NFM simultaneously achieves high‐rate (104.4 mAh g⁻¹ C) excellent (95% capacity after 100 cycles 1 C), outperforming undoped ternary counterparts (NFM). DFT calculations confirm reduced Na⁺ migration barriers lower formation through entropy‐mediated stabilization engineering, synergistically enhancing phase stability + kinetics. This establishes paradigm concurrently optimizing in SIBs cathodes.
