Metal negative electrode ultrasonic charging
Systems and methods for using an ultrasonic vibration generator to apply vibrational energy to a metal negative electrode of a rechargeable battery. In some examples, the application of vibrational energy to the metal negative electrode occurs during a charging event.
1. A method for healing an electrochemical cell, the method comprising ultrasonically vibrating a metal negative electrode in the electrochemical cell, wherein the ultrasonic vibration is applied at a frequency of 20 kHz to 30 kHz, wherein the electrochemical cell is in a battery, wherein the electrochemical cell comprises a solid electrolyte in contact with the negative electrode, wherein the solid electrolyte is a lithium-stuffed garnet.
2. The method of claim 1 , further comprising applying a pressure to the negative electrode.
3. The method of claim 1 , wherein the battery is in a car.
4. The method of claim 1 , wherein the battery is in use in a car.
