Layered oxides are considered promising cathode materials for sodium-ion batteries (SIBs) due to their high energy density, flexible compositions, and low cost. However, they encounter significant challenges, such as multiphase transitions structural instability at voltages, which limit large-scale practical application. In this study, we employed a dual modification strategy involving complex composition doping phosphate coating fabricate the Na0.67Ni0.255Mn0.645(TiMgCuZn)0.1O2@phosphate (D-NNM). The lattice distortion induced by optimizes overall properties of cathode, while forms robust electrode interface through stable P-O bonds. This comprehensive stabilizes phase interfacial structure, thereby enhancing Na+ transport mitigating mechanical degradation surface reactions voltages. Consequently, D-NNM exhibited an initial capacity 136.9 mA·h·g-1 with average potential 3.45 V maintained 85% after 60 cycles 4.4 V, twice that pristine cathode. demonstrated faster diffusion kinetics voltage without any particle cracks observed even 50 cycles. offers protection layered from bulk provides insights into design density cathodes SIBs.

Abstract Iron sulfides are promising anode materials for high‐energy‐density sodium‐ion batteries (SIBs) due to their high theoretical capacity, exceptional safety features, and abundant resources. However, practical application is limited by intrinsic electronic conductivity, low sodium ion diffusion rates, rapid capacity degradation. A novel high‐entropy doping strategy developed using a scalable ball‐milling method form solid solution of doped elements (cation dopants: Ni, Mo, Cr, W, Si; anion dopant: Se) with the primary components (iron sulfur). Simultaneously, expanded graphite (EG) incorporated exfoliated through ball milling provide active sites growth high‐entropy‐doped FeS during subsequent high‐temperature vulcanization process. Systematic experiments calculations demonstrate that substantially improves ionic conductivity as well polysulfide adsorption capabilities. This cation‐ anion‐doped FeS/EG (HED‐FeS 1− x Se /EG) delivers discharge 511 mAh g −1 at 20 . Remarkably, an extremely current density 100 , reversible remains 222.3 After 3000 cycles (40 days) 5 electrode in half‐cell shows specific 832 These findings offer valuable technological insights next‐generation SIBs.
