Solid solutions of Li [Li0.2Ni0.1Co0.2Mn0.5]O-2 were prepared by solvothermal reaction with three different solvents, namely, methanol, ethanol, and 1-propanol. The prepared compounds were subjected to X-ray diffraction (XRD), Raman, Fourier transform infrared, and charge-discharge studies. XRD studies revealed that the prepared compounds are of layered structure with space group R(3) over bar m. The sample which was prepared using 1-propanol as solvent delivered the highest discharge capacity of 205 mAh/g. The electrochemical and structural properties of the prepared compounds are influenced by the physical properties of the solvents. (c) 2006 The Electrochemical Society.
