摘要

钠离子电池研究论文（10.1002/adfm）[202504642]，胡淑志，陈新义，陈汉义，等人研究了一种新型的钠离子电池正极材料P2-Na0.61Ca0.03[mg2 / 9cu1 / 9m2m /3]O2。过渡金属层中的Cu取代在氧氧化还原过程中稳定了O离子，而在碱金属层中掺杂Ca作为结构“支柱”抑制了相变。Na0.61Ca0.03[Mg2/9Cu1/9Mn2/3]O2具有较高的比容量（0.1℃时为205 mAh g−1）、良好的循环稳定性和令人印象深刻的倍率性能（2.5℃时为142 mAh g−1），显示了其作为高能钠离子电池的潜力。

Na-Ion Batteries

In their Research Article (10.1002/adfm.202504642), Shu-Chih Haw, Hsin-Yi Tiffany Chen, Han-Yi Chen, and co-workers develop a novel P2-Na_0.61Ca_0.03[Mg_2/9Cu_1/9Mn_2/3]O₂ cathode material for Na-ion batteries. Cu substitution in transition-metal layers stabilizes O ions during oxygen redox, while Ca doping in alkaline-metal layers acts as structural “pillars” to suppress phase transformation. Na_0.61Ca_0.03[Mg_2/9Cu_1/9Mn_2/3]O₂ exhibits a high specific capacity (205 mAh g⁻¹ at 0.1 C), good cyclic stability, and impressive rate capability (142 mAh g⁻¹ at 2.5 C), demonstrating its potential for high-energy Na-ion batteries.
