Li-Substitution in P′2-Na0.67MnO2 mitigates the anisotropic change of Mn–O bonds and Na/vacancy ordering, and hence significantly promotes its cycling stability and rate capability as a cathode material for sodium-ion batteries.

Jahn Teller Distortion

The partial substitution of manganese by lithium and cobalt ions in 16d octahedral sites enhances the electrochemical cyclability of LiMn2O4upon cycling. The improvement in cycling performance is mainly attributed to the suppression of the Jahn–Teller distortion in the spinel structure. The as-doped spinel Mn oxide has been successfully used as cathode material in flat and flexible lithium battery.
