摘要

由于Na资源的丰富和低成本，Na离子电池（NIBs）具有大规模储能的前景，但其实际应用仍然受到阴极能量密度和循环稳定性的限制。本研究采用CaHPO4 （CP）对o3型NaNi1/3Fe1/3Mn1/3O2 （NFM）阴极进行了体积和界面的协同改性策略，结合Ca掺杂和均匀的NaPO3涂层，提高了结构稳定性和界面鲁棒性。改性阴极（2%CP@NFM）具有优异的性能，在2℃下300次循环保持92%的容量，在5℃下400次循环后没有容量衰减，在1℃下1000次循环保持83%的容量。结构分析揭示了层状氧化物阴极的不可逆相变、气体演化和过渡金属离子溶解问题的显著抑制。这些发现强调了低成本CP修饰策略在实现高性能nib用于可持续能源存储方面的潜力。

Synergistic Bulk and Interface Engineering of Layered Oxide Cathodes for Na-Ion Batteries

Na-ion batteries (NIBs) hold promise for large-scale energy storage due to the abundance and low cost of Na resources, but their practical applications are still limited by the energy density and cycling stability of the cathodes. This study develops a synergistic bulk and interfacial modification strategy for O3-type NaNi_1/3Fe_1/3Mn_1/3O₂ (NFM) cathode using CaHPO₄ (CP), integrating Ca doping and uniform NaPO₃ coating to enhance structural stability and interfacial robustness. The modified cathode (2%CP@NFM) delivers excellent performance, retaining 92% capacity over 300 cycles at 2 C, no capacity decay after 400 cycles at 5 C, and 83% capacity retention over 1000 cycles at 1 C in full-cells. Structural analyses reveal remarkable suppression of irreversible phase transitions, gas evolution, and transition metal ion dissolution issues of layered oxide cathodes. These findings highlight the potential of a low-cost CP modification strategy in achieving high-performance NIBs for sustainable energy storage.
