Description
Lithium ion batteries most commonly use graphite as an anode material. Understanding the dynamical processes of the lithiation and delithiation play a crucial role in understanding performance, degradation of graphite based anodes. Our operando neutron diffraction of LiCoO2/graphite cells showed the occurrence of inhomogeneously delithiated graphite anodes.Phase coexistence of multiple stages is followed by relaxation into a single phase or a two phase mixture close to the mean lithium content.
