Microstructural Investigations of the Layered Cathode Materials LiCoO2 and LiNi1/3Mn1/3Co1/3O2
… studies. P3 phase of CoO2, the end member of the LixCoO2, is found in both chemically and electrochemically delithiated materials. Delithiated LixCoO2 specimens decompose into fine Co3O4 and LiCoO2 particles starting at around 200 °C. This decomposing reaction is proved by in-situ X-ray …

First principles investigation of the thermodynamic and kinetic properties of lithium transition metal oxides
… thermodynamic and kinetic properties of LixCoO2, an important cathode material for rechargeable lithium batteries. In a lithium battery, the lithium concentration x in Lix CoO2 can be varied between O and 1. Such concentration variations result in important changes of the electronic …

Electronic correlations in Lix̳ CoO₂
… understanding of the electronic properties of LixCoO2 using density functional theory (DFT) and the dynamical mean-field theory (DMFT). Three main problems are addressed. First, the influence of hybridization among the eg and oxygen orbitals is studied using DFT and a modified Hubbard model …
