A novel strategy to significantly enhance the initial voltage and suppress voltage fading of a Li- and Mn-rich layered oxide cathode material for lithium-ion batteries

A Li[Li_0.2Ni_0.13Co_0.13Mn_0.54]O₂–xLiNiO₂ composite cathode with a Ni-rich bulk phase and in situ precipitated Ni-rich spinel-like surface phase has been built to enhance the initial voltage and suppress voltage fading during cycling.
