It was thought that oxides could not intercalate Li below 1.5V vs Li+/Li. We recently studied layered LiVO2, which intercalates Li at around 0.25V to form Li2VO2, making it an alternative anode to graphite. Intercalation electrodes operating closer to 1V vs. Li+/Li are highly desirable. They are safer and provide protection to plating Li compared with graphite, while still giving a satisfactory overall cell potential. As a result we have been investigating Li insertion in other LiMO2 systems. Some of these (e.g. M = Mn, Ni) form analogous Li2MO2 compounds whilst others are involved in conversion reactions i.e. where the metal oxide converts to a metal plus Li2O. We propose to investigate the structures of several LiMO2 systems as a function of lithium insertion, both in cases where intercalation occurs and also for conversion reactions.
