Li₂CuSnO₄ and Li₂CuSnSiO₆ were prepared from their precursors compounds using Brij surfactant and a hydrothermal autoclave method. X-ray diffraction characterization revealed that the crystal structures of these compounds were tetragonal. Scanning electron microscope investigation showed the particle size morphology of Li₂CuSnSiO₆ is larger than that of Li₂CuSnO₄. Electrochemical impedance spectroscopy (EIS) explained that Li₂CuSnO₄ cell had higher charge transfer resistance (R_ct = 2936Ω) than that of Li₂CuSnSiO₆ (38Ω). Furthermore, the reversible specific discharge capacity of the Li₂CuSnSiO_{6 …}
