摘要: We report, for the first time, a simple and novel synthesis of Li-rich layered-spinel core–shell heterostructure (L@S core–shell) via evaporation-induced self-assembly (EISA) Ni-doped Li4Mn5O12 nanoparticles (Li4Mn4.5Ni0.5O12) onto surface layered Li[Li0.2Mn0.54Ni0.13Co0.13]O2 (LMNCO) without using any surfactant during coating process. The resultant L@S as cathode in lithium ion batteries demonstrates significantly improved specific capacity, cycling performance rate capability compared to pristine LMNCO.
