WebMay 31, 2024 · Li 2 MnO 3 is considered as one of the candidates for Li-rich cathode material of next-generation lithium-ion batteries because of its high energy density. Due to the synthesis environments and migration of Mn in the charging/discharging cycles, Mn/Li disordered mixing in Li/transition-metal layers of Li 2 MnO 3 is frequently observed and … WebThe α-NaFeO 2-type layered structure is also classified as an O3-type layered structure according to Delmas' notation. 3 Herein, ... The O1 phase transition is, therefore, allowed only for a fully delithiated phase, or a small number of Li ions is probably found at neighboring tetrahedral sites, which share edges with the CoO 6 octahedra.
