  • Method and system for improved performance of silicon anode containing cells through formation
    Patent number: 11695104
    Abstract: Systems and methods for improved performance of silicon anode containing cells through formation may include a cathode, electrolyte, and silicon containing anode. The battery may be subjected to a formation process comprising one or more cycles of: charging the battery at a 1 C rate to 3.8 volts or greater until a current in the battery reaches C/20, and discharging the battery to 2.5 volts or less. The battery may comprise a lithium ion battery. The electrolyte may comprise a liquid, solid, or gel. The anode may comprise greater than 70% silicon. The battery may be discharged until the current reaches 0.2 C. The battery may be discharged at a 1 C rate or at a 0.2 C rate. The battery may be in a rest period between the charge and discharge.
