Effect of power ultrasound on resource recycling and utilization of spent lithium-ion batteries:A review
In recent years,with the rapid development of the electric vehicle industry,the retention of spent lithium-ion batteries,which are commonly used in electric vehicle power batteries,has also surged.Resourceful recycling of spent lithium-ion batteries can not only avoid the environmental problems caused by solid waste piles,but also provide raw materials for the manufacturing of new batteries.Power ultrasound has been shown to be an effective means to enhance the resourceful recycling of spent lithium-ion batteries,and the unique physical and chemical effects are the main mechanisms that produce the enhancement effect.Based on the introduction of ultrasonic cavitation theory,the pathway of ultrasonic enhancement of spent lithium-ion batteries resource-based recycling is discussed,and the application and research progress of ultrasonic technology in the separation process of metal collector and electrode materials,the resource-based recycling process of electrode materials and the repair process of electrode materials of spent lithium-ion batteries are reviewed.Finally,the shortcomings of ultrasonic assisted technology in industrial application are discussed,and the prospect of industrial application of ultrasonic in the resource recycling and utilization of spent lithium-ion batteries is prospected.
