Abstract本发明公开了一种P2型层状过渡金属氧化 物及其制备方法和应用。该P2型层状过渡金属氧 化物的化学式为KNaMnxNiyZnzO2,其中,0<x<1, 0<y<1,x+y+z=1。其制备方法包括:将前驱体、 ZnO、含钠熔盐和含钾熔盐的均匀混合物或将前 驱体、含钠熔盐和含钾熔盐的均匀混合物进行煅 烧;其中,前驱体为MnxNiyCO3。通过在P2型金属氧 化物中,引入钠离子,进而在电化学离子交换反 应过程中,一定程度的钠离子残留在层状结构 中,起到稳定层状结构,激活过渡金属离子的氧 化还原反应,提高循环性能和速率性能。当含有 锌离子掺杂时,可进一步降低活化能,促进界面 扩散动力学,有效抑制材料中的相变,进而提升 材料性能。
