Abstract

High energy nickel manganese cobalt oxide materials (HENMC) are one of the most viable cathode materials for a high energy density lithium ion battery (LIB), but they contain expensive and toxic cobalt (Co). We synthesized Co-free high energy nickel manganese oxide cathode materials (HENM) via a solid state reaction method and a coprecipitation method. Their structural and electrochemical properties were comparatively investigated using X-ray diffraction spectroscopy (XRD), scanning electron microscopy (SEM), inductively coupled plasma (ICP), electron probe micro-analysis (EPMA), particle size analysis (PSA) and electrochemical impedance spectroscopy (EIS). The co-precipitated HENM and the solid state fabricated HENM showed high capacities of 250 mAhg^-1 and 240 mAhg^-1, respectively. It suggests that the solid state fabricated method of HENM would be a good candidate for practical application as well as the co-precipitated one.
