  "textContent": "A method for periodic deep discharge to extract lithium in silicon-dominant anodes may include providing a cell comprising a cathode, a separator, and a silicon-dominant anode; charging and discharging the cell through a plurality of cycles; and, following the plurality of cycles, performing one or more deep discharge cycles, where each of the one or more deep discharge cycles comprises a cutoff voltage below a normal operating voltage range of the cell. The one or more deep discharge cycles may comprise a C/10 or lower or C/20 or lower discharge current. The one or more deep discharge cycles may include a cutoff voltage of 3.2 V or less, a cutoff voltage of 2.5 V or less, a cutoff voltage of 1.5 V or less, or a cutoff voltage of 1 V or less. The cell may be configured at a higher temperature during the one or more deep discharge cycles.",
