Title: Simulation of First-Charge Oxygen-Dimerization and Mn-Migration in Li-Rich Layered Oxides xLi2MnO3 ·(1 – x )Li MO2 and Implications for Voltage Fade

Journal Article · · Journal of Physical Chemistry. C

The instabilities of Li-rich layered oxide xLi2MnO3•(1-x)LiMO2 (lithium-ion-battery cathode materials) during the first charge are investigated using first-principles dynamical simulation. To complement our earlier simulations for (x = 0.4, M = Ni0.5Mn0.5), we address here: pure Li2MnO3; small x; M compositions that include Co; a composite with Co spinel: Li2MnO3•Li2M2O4; a Li2MnO3 slab. Lastly, we discuss how the threshold fraction f of Li2(1-f)MnO3 delithiation at which instabilities occur at the surface, fth(surface), differs from that in the bulk, fth(bulk). Approaches to inhibit voltage fade are discussed.
