Iron-based phosphate cathode materials exhibit excellent cost-effectiveness and performance advantages, making them promising for large-scale applications in sodium-ion batteries. However, industrial efforts to enhance the energy density of battery packs by coating high-loading electrodes often lead poor wettability low conductivity, significantly impacting performance. Herein, this work successfully fabricated an situ carbon-coated porous Na4Fe1.55(PO4)P2O7 (NFP/600) cathode, which exhibits a unique capillary effect when contact with electrolyte, enhancing NFP/600 electrode. While structure carbon improve ion electron transport capabilities, improving kinetic Consequently, initial discharge capacity reaches 97.6 mAh g-1 at rate 5 C, retention 84.9 after 2500 cycles. Even loading exceeding 10 mg cm-2, electrode achieves specific 100.83 1 retaining 98.4% its 460 Furthermore, full cell pairing hard demonstrated 93.9 maintaining stable cycling over 200 These findings provide pathway design low-cost, high-performance materials.
