Anode sheets of spent lithium-ion batteries were taken for research, and an L₂₅(5⁴) orthogonal test was employed to investigate the effects of ultrasonic temperature, ultrasonic time, ultrasonic frequency and solid-liquid ratio on the separation efficiency of graphite and copper foil in a system with an addition of 0.5% surfactant. A system without surfactant was taken as the control group. The results show that the graphite separation efficiency reaches 95.75% in a system with an addition of 0.5% surfactant, by ultrasonic separation at 90 ℃ for 15 min with a frequency of 100 kHz and solid-liquid ratio of 1∶9. The recovered graphite is basically consistent with those of standard graphite in terms of the XRD diffraction peaks and has a low proportion of disordered structure. The recovered copper foil exhibits favorable mechanical properties, with a tensile strength of 180-190 MPa, and its carrier mobility is 35.68 cm²／(V·s), indicating excellent electrical conductivity.

以废旧锂离子电池负极片为研究对象，采用L₂₅（5⁴）正交试验，在添加0.5%表面活性剂的体系中，考察超声温度、超声时间、超声频率、固液比对石墨和铜箔分离率的影响，并设置无表面活性剂体系作为对照。结果表明，在表面活性剂添加量0.5%、超声温度90 ℃、超声时间15 min、超声频率100 kHz、固液比1∶9条件下，石墨分离率可达95.75%。回收石墨的XRD衍射峰与标准石墨基本一致，无序结构占比较低。回收铜箔抗拉强度为180~190 MPa，力学性能良好；载流子迁移率为35.68 cm²/（V·s），具备良好的导电性能。
