The potential of lithium transition metal compounds such as oxides, sulfides, and phosphates (Figures 3A,B) is lower than the reduction potential of the aprotic electrolyte, and their electrochemical potentials are largely determined by the redox energy of the transition metal ion (Yazami and Touzain, 1983; Xu et al., 1999; Egashira et al., 2001).
