Linking Local Atomic Structure and Carbon Network Architecture to Electrochemical Performance and Na⁺ Diffusivity in Na₄VMn(PO₄)₃/C Cathodes.

ABSTRACT: Na₄VMn-(PO₄)₃ is a promising cathode material for sodium-ion batteries due to its high operating voltage, structural robustness, and open three-dimensional framework that supports efficient Na⁺ transport. However, its practical deployment is limited by poor intrinsic electronic conductivity and structural instability under cycling. To address these limitations, Na₄VMn-(PO₄)₃/carbon (Na₄VMn-(PO₄)₃/C) composites were investigated, focusing on the interplay between carbon network architecture and local atomic structure. Using advanced characterization techniques, this study reveals that the degree of distortion in MnO₆ and VO₆ octahedra, along with the continuity
