Dual-strategy modification on P2-Na 0.67 Ni 0.33 Mn 0.67 O 2 realizes stable high-voltage cathode and high energy density full cell for sodium-ion batteries

[摘要] 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.
