α-NaMnO2(空间群C2/m)和β-NaMnO2(空间群Pmnm)可以分别在低温和高温环境下合成.由于Mn3+(t2g3eg1)严重的Jahn-Teller畸变导致NaMnO2的容量衰减非常严重,可采用Mg或Li部分替代Mn可以有效抑制Jahn-Teller效应[94-95]. Na2/3[Ni1/3Mn2/3]O2具有较高的工作电压和比容量[96].但是Na+脱出会引起P2相向O2相的转变并造成钠空位....特别是利用多金属离子的协同效应,开发多金属氧化物.例如,LIU等[101]设计了O3型NaMn0.48Ni0.2Fe0.3Mg0.02O2,其中Mg2+的加入不仅增大了层间距,提高了Na+的扩散动力学和倍率性能,同时有效抑制了锰的Jahn-Teller效应.因此,与无Mg掺杂样品相比,在5C的倍率下可以获得40 mA·h/g的可逆容量.
