  "abstract": "Manganese-based sodium super ionic conductor-type cathode materials, leveraging the multielectron redox activity of manganese, represent a promising pathway toward high-energy-density sodium-ion batteries (SIBs). However, the unavoidable generation of Mn³⁺(3d⁴) species during charge-discharge processes, characterized by asymmetric eg orbital occupancy, triggers octahedral symmetry breaking. This inherent electronic structural instability creates a fundamental contradiction between achieving high energy density and ensuring long cycle life that remains inherently difficult to reconcile. Here, we report an electron-donor-mediated (EDM) mechanism that suppresses Mn³⁺-induced octahedral distortion while preserving high-spin functionality. As electron-donating Fe³⁺ and V³⁺ are incorporated, Mn³⁺ 3d electrons undergo partial delocalization. This electronic redistribution promotes orbital interactions between neighboring transition metal sites through the transition metal-oxygen framework, driving the eg orbitals toward a more symmetric occupation and suppressing octahedral distortion. The EDM-modified cathode demonstrates a high energy density of 492.06 Wh kg⁻¹. It delivers 178.8 mAh g⁻¹ at 0.1 C and retains 80.2% of its capacity over 2000 cycles at 10 C, paving a novel pathway toward next-generation high-performance SIBs cathode materials.",
