Abstract

Abstract : Schematic illustration of a facile preparation of a L@S core–shell heterostructure. 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 Li4 Mn5 O12 nanoparticles (Li4 Mn4.5 Ni0.5 O12 ) onto the surface of layered Li[Li0.2 Mn0.54 Ni0.13 Co0.13 ]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.
