摘要

采用Mg2+掺杂与ZrO2表面改性相结合的双重策略对P2-Na0.67Ni0.33Mn0.67O2进行了电化学性能优化。双策略改性抑制了受损的P2-O2相变和阴极与电解质的副反应，实现了钠离子电池稳定的高压阴极高能量密度全电池。

Dual‐strategy modification on P2‐Na_0.67Ni_0.33Mn_0.67O₂ realizes stable high‐voltage cathode and high energy density full cell for sodium‐ion batteries

A dual strategy of Mg2+ doping integrated with ZrO2 surface modification is applied on P2-Na0.67Ni0.33Mn0.67O2 to optimize its electrochemical performance. The damaged P2–O2 phase transition as well as side reactions between cathode and electrolyte are both suppressed after dual-strategy modification, thus realizing stable high-voltage cathode and high energy density full cell for sodium ion batteries.
