Embodiment 1
[0046] a. Cut the waste rare earth capacitor battery and separate the battery cell and parts:
[0047] Use a laser cutting machine to cut waste rare earth capacitor batteries, take out the battery core including the plate and diaphragm, and take out the parts including the battery case, top cover, safety valve, pole, lug, nut, flat gasket and gasket.
[0048] b. Ultrasonic soak the cell with NaOH, and then separate the diaphragm and nickel foam to obtain the soaking solution:
[0049] Soak the cell and pure water at a mass ratio of 1:0.8, then add NaOH for ultrasonic soaking, the ratio of NaOH to pure water is 0.1:1, NaOH is measured in moles, and pure water is measured in L. Use 2000W ultrasonic power to intermittently ultrasonicate 4 times, the cumulative time is 20min, the soaking temperature is 75°C, and the soaking time is 1h, then take out the foamed nickel from which the electrode material has been separated, wash and dry, take out the diaphragm, wash and dry, and the r...
