Preparation, Characterization, and Electrochemical Performance of Li[sub 2]CuSnO[sub 4] and Li[sub 2]CuSnSiO[sub 6] Electrodes for Lithium Batteries

Lithium copper tin silicon oxide was prepared from their precursor compounds using Brij surfactant and different sources of Si such as , SiC, and . A hydrothermal autoclave method was used in the first stage of the preparation. X-ray diffraction characterization revealed that the crystal structures of these compounds were tetragonal. Scanning electron microscope investigation showed that the particle size morphology of is larger than that of . Electrochemical impedance spectroscopy explained that the cell prepared from the electrode using precursor had a lower charge-transfer resistance than that of . Furthermore, the reversible specific discharge capacity of the cell was 870 mAh/g in comparison with 780 mAh/g for the cell after 100 cycles.
