Fig. 2: TEM and electrochemistry of the layered P2 phases.

SAED patterns of a P2-Na2/3Ni1/3Mn2/3O2 and b P2-Na2/3Ni0.3Mn0.7O2 from [001] zone axis, and the corresponding STEM-HAADF images along the [001] direction are displayed at the insets. c Raman spectra, d rate performance and e, f CV curves of P2-Na2/3Ni1/3Mn2/3O2 and P2-Na2/3Ni0.3Mn0.7O2 samples at different scanning rates between 2.0 and 4.0 V.
