Composite ceramic cathodes represented by the formula (1-x-y) LiNi1/3Co1/3Mn1/3O2 center dot xLi(2)MnO(3)center dot yLiCoO(2) were studied. A ternary compositional diagram was built with these ceramic materials as end-members, and selected points were chosen to represent the compositional space. Synthesized ceramic composite materials were investigated as to whether integration of structurally compatible units leads to improved electrochemical performance. Detailed structural (X-ray diffraction - XRD), elemental (X-ray photoelectron spectroscopy-XPS), microstructure (Scanning electron microscopy - SEM), and electrochemical (galvanostatic testing of half-cells) studies were performed and are presented. Within eight samples studied three compositions are found to exhibit first discharge capacity of around 230 mAh/g. (C) 2017 Hydrogen Energy Publications LLC. Published by Elsevier Ltd.
