Abstract
⺠In situ Raman spectroscopy of layered solid solution of Li2MnO3-LiMO2 (M = Ni, Mn, and Co). ⺠Impedance decrease steadily and reaches minimum at 4.47 V ⺠Less steep increase in impedance as cell voltage traversed the first charge 4.5 V plateau. ⺠Lithium extraction occur from transition metals as well as lithium layers in 4.1-4.4 V voltage range. ⺠Extraction of oxygen along with lithium ions from the transition metal layers takes place after 4.5 V.
