Structural insights into the formation and voltage degradation of lithium- and manganese-rich layered oxides
The authors here look into the phase transitions in Li-/Mn-rich layered cathode materials during synthesis and cycling. It is revealed that the Li-rich layered structure tends to transform to a Li-poor spinel phase via an intermediate Li-containing rock salt phase, with release of lithium/oxygen.
