Study on the Fabrication and Performance of Mo-WO<sub>3</sub>//Co<sub>3</sub>O<sub>4</sub>–NiO Energy Storage Devices

Lithium-ion batteries are widely used in energy storage applications. In this work, Mo-doped WO<sub>3</sub> (Mo-WO<sub>3</sub>) thin films were prepared by a hydrothermal method, and their electrochemical storage properties were studied. Among them, the 2%Mo-WO<sub>3</sub> thin film showed the best storage performance. Meanwhile, Co<sub>3</sub>O<sub>4</sub>-NiO codeposited thin films were prepared by electrodeposition method, and their electrochemical storage properties were also studied. The 2%Co<sub>3</sub>O<sub>4</sub>-NiO thin film showed the best storage performance. A Mo-WO<sub>3</sub>//Co<sub>3</sub>O<sub>4</sub>-NiO electrochemical storage device was constructed with the Mo-WO<sub>3</sub> thin film as the cathode and the Co<sub>3</sub>O<sub>4</sub>-NiO thin film as the anode. This work shows that this device has an obviously improved areal capacitance (111.5 mF/cm<sup>2</sup>) and has 88% capacity retention after 500 charge and discharge cycles.

Abstract

Lithium-ion batteries are widely used in energy storage applications. In this work, Mo-doped WO<sub>3</sub> (Mo-WO<sub>3</sub>) thin films were prepared by a hydrothermal method, and their electrochemical storage properties were studied. Among them, the 2%Mo-WO<sub>3</sub> thin film showed the best storage performance. Meanwhile, Co<sub>3</sub>O<sub>4</sub>-NiO codeposited thin films were prepared by electrodeposition method, and their electrochemical storage properties were also studied. The 2%Co<sub>3</sub>O<sub>4</sub>-NiO thin film showed the best storage performance. A Mo-WO<sub>3</sub>//Co<sub>3</sub>O<sub>4</sub>-NiO electrochemical storage device was constructed with the Mo-WO<sub>3</sub> thin film as the cathode and the Co<sub>3</sub>O<sub>4</sub>-NiO thin film as the anode. This work shows that this device has an obviously improved areal capacitance (111.5 mF/cm<sup>2</sup>) and has 88% capacity retention after 500 charge and discharge cycles.
