Abstract
A solid electrolyte interface is grown on a silicon monoxide electrode in a battery cell, including by charging the battery cell up to a first voltage while the battery cell is uncompressed in order to partially grow the solid electrolyte interface. After partially growing the partial solid electrolyte interface, the battery cell is rested. After resting the battery cell, the battery cell is charged to a second, higher voltage while the battery cell is compressed in order to further grow the partially grown solid electrolyte interface. After the solid electrolyte interface is grown on the silicon monoxide electrode, the battery cell is charged for one or more cycles while the battery cell is compressed.
