| Abstract: | LiMn1.8Cu0.2O4 was investigated in order to improve the electrochemical properties of LiMn2O4. We report the synthesis and characterization of materials prepared by solid-state reaction. The structural properties evaluated
by the X-ray diffraction and vibrational spectroscopy show that a single phase was formed. Conductivity of LiMn1.8Cu0.2O4 cathode is found to be 8×10−6 S/cm at 25 °C. The cyclic voltammetry data shows the reversibility of the electrode material.
