P2-type layered Na0.66Ni0.26Zn0.07Mn0.67O2 (NNZM) is expected to be a competitive alternative to lithium layered oxide due to its high-energy-density, low production cost, and high-speed Na+ ion transport channels. However, it is still necessary to further improve its air stability and cycle life to...
