Abstract
Systems and methods for silicon dominant lithium-ion cells with controlled lithiation of silicon may include a cathode, an electrolyte, and an anode. The anode may include silicon lithiated at a level after discharge that is configured to be above a minimum threshold level, where the minimum threshold lithiation is 3% silicon lithiation. The lithiation level of the silicon after charging the battery may range between 30% and 95% silicon lithiation, between 30% and 75% silicon lithiation, between 30% and 65% silicon lithiation, or between 30% and 50% silicon lithiation. The lithiation level of the silicon after discharging the battery may range between 3% and 50% silicon lithiation, between 3% and 30% silicon lithiation, or between 3% and 10% silicon lithiation. The minimum threshold level may be a lithiation level below which a cycle life of the battery degrades. The electrolyte may include a liquid, solid, or gel.
