We investigated the relation between crystal structure, electronic states and electrode performance of LiMn2-xMxO4 (M = Zn, Ni etc.) as cathode materials for lithium ion secondary batteries. The cycle performance is improved by substitution of Mn with M. The crystal structure was determined by Rietveld analysis using powder neutron diffraction. The electron density distribution was obtained by XRD using MEM/Rietveld method. From the results, the stability of the host structure is important for cycle performance.
