Abstract Mn‐containing sodium superionic conductor (NASICON) compounds have shown considerable potential as cathode for sodium‐ion batteries (SIBs) owing to higher working voltage (V 5+ /V 4+ : 3.9 V), lower cost, and toxicity compared full vanadium‐based NASICON Na 3 V 2 (PO 4 ) . Taking 3.3 1.7 Mn 0.3 (NVMP) an example, its practical application is still restricted by poor electronic conductivity, sluggish intrinsic + diffusion, high‐voltage stability. In this work, a high entropy strategy proposed develop 1.613 (Cr, Fe, Co, Ni, Zr) 0.1 (HE‐NVMP) not only enabling more rapid migration but also significantly improving deep desodiation Based on theoretical calculations experimental findings, such modification can efficiently alter the coordination environments of both V/Mn sites reducing diffusion energy barrier, increasing occupancy at Na(2) sites, consolidating structure Thus, obtained HE‐NVMP delivers superior high‐rate capability (91.7 mAh g −1 up 50 C excellent cycling performance (capacity retention: 81.2%) after 10 000 cycles 20 cutoff 4.1 V. More importantly, exhibits storage properties (4.5 V) with electrochemical polarization 75% reduction 1 capacity retention 80.3% 2000 pristine counterpart, indicating great rechargeable overcharge resistance capability.

NaNi1/3Fe1/3Mn1/3O2 (NFM111) is widely used because of its high theoretical specific capacity and excellent environmental adaptability. In our previous study, NFM111 was synthesized by solid-phase ball milling comprehensively evaluated. It found that has NiO in the bulk phase, which may lead to instability structure affect properties material. To solve this problem, we prepared spherical coprecipitation prilling work. The morphology obtained, content peaks reduced. At same time, tap density particles rate performance material are effectively improved. work, advantages disadvantages two methods for preparing materials analyzed comparing their properties. provides some reference subsequent production research NFM111.
