摘要
CONSPECTUS:Li-rich layered oxides have received extensive attention as promising high-energy-density cathodes for next-generation Li-ion batteries.Different from traditional cathodes such as LiCoO2,LiFePO4,and Li2MnO4,Li-rich oxides generally can harvest superior discharge capacities exceeding 250 mAh g−1,which originated from the contribution of oxygen redox chemistry.However,lattice oxygen release and irreversible TM transition would induce severe structure distortion and capacity degradation as well as voltage attenuation within Li-rich cathodes during electrochemical processes,which greatly limits their industrial applications in next-generation Li-ion batteries.
