Recycling of cathode material from spent lithium ion batteries using an ultrasound-assisted DL-malic acid leaching system

•Ultrasound enhancement is novely applied for leaching process.•A closed-loop process is developed to recycle spent cathode materials.•The mechanism of ultrasound-assisted leaching is explained. Herein, a novel process involving ultrasound-assisted leaching developed for recovering Ni, Li, Co, and M...
