Abstract

A splitting of two O3 phases, rather than the often observed O1 phases in the conventional LiCoO<sub>2</sub> electrode, was discovered in the LiNi<sub>0.85</sub>Co<sub>0.10</sub>Mn<sub>0.05</sub>O<sub>2</sub> at high-voltage region (&gt;4.6 V) by <italic>in situ</italic> high-resolution synchrotron radiation diffraction.
