A patent application (Publication Number: US20240039055A1) describes a method for ultrasonically vibrating a metal negative electrode in an electrochemical cell. The method involves vibrating the metal negative electrode while simultaneously charging the cell. The charging process occurs at various temperatures ranging from -30°C to 80°C, and the metal negative electrode can be lithium, sodium, or zinc. The solid electrolyte used can be sulfide-based, garnet-based, or borohydride-based. Additionally, pressure can be applied to the metal negative electrode during the process.

Furthermore, the patent application details a method for charging a battery with a metal negative electrode by vibrating the battery at ultrasonic frequencies and charging it concurrently. Pressure can also be applied to the metal negative electrode during this process. The charging current can vary, and various parameters such as voltage, current, impedance, resistance, pressure, temperature, evolved gases, or physical deformations can be measured. The application also mentions the use of the method in creating electrochemical cells with lithium-metal negative electrodes and their application in batteries, cars, and other devices.
