Title: First-charge instabilities of layered-layered lithium-ion-battery materials

Dynamical simulation at 1000 K shows the migration of oxygen ions in delithiated Li 7/6-xNi 1/4Mn 7/12O 2(withx= 1) from oxygen layers (lower panel, att= 0) to form O–O pairs (upper panel att= 35 ps) thereby lowering the energy of charged cathode material.
