Research Abstract

We investigated the battery properties and structures of composite cathode materials of Li2MnO2-LiCoO2 systems for lithium-ion batteries. The electrochemical capacities can be controlled between 150 – 300 mAhg-1 by regulating the Co contents. The XRD, TEM, and neutron diffraction data showed that the structures also depend on the Co contents; composites with a low Co content are a monoclinic structure with the space group symmetry of C2/m, whereas composites with a high Co content are a rhombohedral one of R-3m. For the samples after charge-discharge cycles, not only disordering Li and Mn atoms but also coexistence of C2/m and Fd-3m phases. Furthermore, for the samples with a high Co content, the phase of R-3m is also observed. These behaviors are related to the cycle numbers and upper voltage for the charge processes.
