Abstract

Lithium-ion batteries are widely used in energy storage applications. In this work, Mo-doped WO3 (Mo-WO3) thin films were prepared by a hydrothermal method, and their electrochemical storage properties were studied. Among them, the 2%Mo-WO3 thin film showed the best storage performance. Meanwhile, Co3O4-NiO codeposited thin films were prepared by electrodeposition method, and their electrochemical storage properties were also studied. The 2%Co3O4-NiO thin film showed the best storage performance. A Mo-WO3//Co3O4-NiO electrochemical storage device was constructed with the Mo-WO3 thin film as the cathode and the Co3O4-NiO thin film as the anode. This work shows that this device has an obviously improved areal capacitance (111.5 mF/cm2) and has 88% capacity retention after 500 charge and discharge cycles.

Mo-WO3//Co3O4-NiO储能器件的制备与性能研究

锂离子电池广泛应用于储能领域。本文采用水热法制备了mo掺杂WO3 （Mo-WO3）薄膜，并对其电化学存储性能进行了研究。其中，2%Mo-WO3薄膜的存储性能最好。同时，采用电沉积法制备了Co3O4-NiO共沉积薄膜，并对其电化学存储性能进行了研究。2%Co3O4-NiO薄膜的存储性能最好。以Mo-WO3薄膜为阴极，Co3O4-NiO薄膜为阳极，构建了Mo-WO3//Co3O4-NiO电化学存储装置。研究表明，该器件的面电容（111.5 mF/cm2）有明显提高，500次充放电循环后容量保持率为88%。
