Abstract

Li2NixMn1-xSiO4 (x = 0, 0.2, 0.4, 0.6, 0.8 and 1) samples were prepared by solid state process. The structure of prepared samples of Li2NixMn1-xSiO4 is characterized by XRD. The crystal structure of the samples is orthorhombic having space group Pmn2(1). SEM investigations are carried out explaining the morphology of powders of these samples. Furthermore, electrochemical impedance spectra measurements are applied. The highest conductivity is achieved with the cell prepared from Li2Ni0.2Mn0.8SiO4 compound. Cyclic voltammetric measurements are carried out for Li2NixMn1-xSiO4 material between 0.1 and 4.5 V vs. Li+ with scan rate 0.1 mVs(-1). It is observed that Li/Li2Ni0.2Mn0.8SiO4 cell has initial capacity of 160 mAhg(-1). The cycle life performance is carried out for Li2NixMn1-xSiO4 cells. The prepared cells gave average capacities between 100 and 150 mAhg(-1).
