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