Abstract Sodium superionic conductor (NASICON)‐type Na 3 V 2 (PO 4 ) (NVP) has emerged as a pivotal cathode material for the development of high‐durability sodium‐ion batteries, owing to its distinctive 3D open framework and exceptional chemical stability. Enhancing electrochemical performance NVP through incorporation conductive materials precise control pore structure requires refining optimizing synthesis methodologies. In this study, robust composites combined with dextrin‐derived carbon (D‐NVP/Dex) nanotubes (D‐NVP/CNT) are developed stable cycling characteristics high energy densities, exhibiting capacities 99.0 93.0 mA h g −1 , respectively, at 1.0 C after 300 cycles, via two‐step approach utilizing spray techniques. These structural features, including conformal layer encapsulating particles connections formed CNT networks, validated enhance their electrical ionic conductivities, demonstrated by evaluations both half‐cell symmetric full‐cell configurations. Specifically, D‐NVP/Dex||D‐NVP/Dex D‐NVP/Dex||P‐NVP batteries exhibit excellent cyclability, achieving 46.5 49.0 150 cycles 0.5 C.
