Abstract Sodium‐ion batteries (SIBs) have emerged as a promising candidate for next‐generation energy storage systems owing to their inherent cost advantages. Nevertheless, the practical implementation of SIBs faces critical limitations in density compared commercial lithium‐ion (LIBs), posing significant barrier widespread applications. Enhancing through both development high specific cathode materials and elevated operational voltages represents dual‐pronged strategic approach. However, voltage elevation typically accelerates system degradation multiple mechanisms including accelerated electrolyte decomposition, loss reactive oxygen, particle cracking, transition metal cation (TM n+ ) migration deposition. This review summarizes key challenges from operated at high‐voltages, discuss main strategies overcome these terms layered oxide design. The purpose this is shed light on fundamental science behind challenges, provide potential solutions achieving goal high‐energy SIBs.

LiMn0.6Fe0.4PO4 is limited in practical applications due to its low electronic conductivity and slow Li+ diffusion rate. Therefore, Cu doping was applied modify LiMn0.6Fe0.4PO4, the mechanism of Cu2+ "three-function" synergistic enhancement cathode material performance explored. Compared undoped sample (LMFP), Cu-doped (LMFP-Cu 1%) exhibited significantly improved coefficient. First-principles calculations also confirmed high barrier LiMn0.6Fe0.4PO4@C. Additionally, LiMn0.6Fe0.39Cu0.01PO4@C demonstrated excellent rate cycling stability, with discharge capacities 160.3 mA h g-1 121.2 at 0.1 2C rates, respectively. After 200 cycles 1C rate, capacity retention 92.5%. The first principle calculation DFT can help show that introduction effectively reduce intrinsic Li+, situ XRD analysis revealed good structural stability reversibility. incorporation represents a promising approach improving lithium storage capabilities materials.

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.
