Title: Performance improvement of Li-rich layer-structured Li 1.2 Mn 0.54 Ni 0.13 Co 0.13 O 2 by integration with spinel LiNi 0.5 Mn 1.5 O 4

Abstract

Li-rich layered Li 1+xMnyM 1-x-yO 2 (or denoted xLi 2MnO 3center dot 1-xLiMO 2, M = Ni, Co, Mn, etc.) are promising cathode materials for high energy-density Li-ion batteries. However, their commercial applications suffer from problems such as a drop in the capacity and discharge voltage during cycling. In this work, the cycling performance of a layered oxide Li 1.2Ni 0.13Co 0.13Mn 0.54O 2 is improved by integration with spinel LiNi 0.5Mn 1.5O 4 to obtain a layered-spinel composite. Characterization by powder X-ray diffraction (XRD), high resolution transmission electron microscopy (HRTEM) as well as cyclic voltammetry (CV) indicates that delayed degradation of layered Li 2MnO 3 and the suppressed growth of LiMn 2O 4-like spinel are responsible for the performance improvement.
