Impact of O3/P3 phase transition on the performance of the NaxTi1/6Mn1/6Fe1/6Co1/6Ni1/6Cu1/6O2 cathode material for Na-ion batteries

Ordering in the transition metal sublattice in the O3 phase affects the density of states near E F . Due to the low conductivity of the O3 phase its presence causes stronger polarization of the electrode and makes P3 → O3 phase change unfavourable.
