Detailed Studies of a High-Capacity Electrode Material for Rechargeable Batteries, Li2MnO3−LiCo1/3Ni1/3Mn1/3O2
TL;DR: Electrochemical oxidation/reduction data show that simultaneous oxygen and lithium removal at the voltage plateau upon initial charge causes the structural rearrangement, including a cation migration process from metal to lithium layers, which is consistent with the mechanism proposed in the literature related to the Li-excess manganese layered oxides.
