Abstract Lithium ion batteries (LIBs) account for the majority of the secondary battery market and it repeats charging and discharging. In the case of Cu2O among the anode materials, it has been studied as a anode of a LIBs with a higher capacity and abundant resources than other transition metal oxides. However, since it has the characteristic of conversion reaction with lithium ion, a severe volume change occurs during charging and discharging, resulting in a drastic decrease in battery life. Also, it has a low electric conductivity. Herein, we synthesized carbon coated copper oxide (Cu2O@C) as an anode material to overcome these disadvantages. The Cu2O electrode was synthesized through the carbonization of the polymer used while controlling the structure using the polymer. It was confirmed that the formed electrode was an octahedral nanostructure having a core@shell structure. Also, Cu2O@C used as anode of LIB underwent structural and electrochemical analysis.
