Ternary Zn–Co–Ni alloy film electrode as an anode has been investigated, for the first time, for the purpose of electrochemical lithium storage in lithium-ion batteries. In this study, the ternary Zn–Co–Ni alloy film electrode is prepared by electroplating method. The electrodes were examined using X-ray diffraction (XRD), FE-SEM with EDX, and impedance studies. The electrochemical results demonstrate that the Zn–Co–Ni alloy film electrode delivers an initial discharge capacity of 281 mAh g−1 and improves to 650 mAh g−1 at the end of 30th cycling with no capacity fading at 0.1 C rate. The charge–discharge properties of the Zn–Co–Ni alloy film electrode are as follows: insertion capacity of 650 mAh g−1 and delithiation capacity of 512 mAh g−1 in the 30th cycling, coulombic efficiency of about 80.0% and good cycling behavior. The results suggest that the ternary Zn–Co–Ni alloy thin film electrode obtained via electroplating shows a good candidate anode material for lithium-ion batteries.
• Ternary Zn–Co–Ni alloy film electrode has been attempted, for the first time, to investigate its availability for lithium-ion batteries.
• The initial discharge capacity is 281 mAh g−1 and improves to 650 mAh g−1 at the end of 30th cycling with no capacity fading.
• The coulombic efficiency in the discharge and charge processes is maintained as high as approximately 80.0%, except for the initial several cycles, at 0.1 C current rate.
