Abstract
Systems and methods are provided for algorithm-optimized voltage and/or current windows for lithium-silicon batteries. A lithium-ion cell may be managed, with the managing including controlling voltage and/or current of the lithium-ion cell using an enhanced algorithm. The controlling includes adjusting voltage and/or current limits applied during one or both of charging and discharging of the lithium-ion cell, and the enhanced algorithm is configured to control a voltage range and/or a current range of the lithium-ion cell to maximize a combination of one or more variable associated with the lithium-ion cell including one or more of cycle life, energy density, cumulative capacity before end of life, and cumulative energy before end of life. The lithium-ion cell may be a silicon-dominant cell having a silicon-dominant anode with silicon >50% of active material of the anode, and the enhanced algorithm may be configured based on characteristic(s) unique to silicon-dominant cells.
