Dislocation and oxygen-release driven delithiation in Li2MnO3

Dislocation and oxygen-release driven delithiation in Li2MnO3

The delithiation process in lithium excess cathode material of Li2MnO3 has remained unclear. Here, the authors report that delithiation is governed by the climb motion of dislocations with the aid of oxygen-release, determined directly by atomic-resolution STEM imaging and spectroscopy.
