    摘要： Systems and methods are provided for state-of-health models for lithium-silicon batteries. State-of-health (SOH) of a lithium-ion cell may be assessed, with the assessing including calculating the state-of-health (SOH) using an enhanced state-of-health (SOH) model, with the enhanced state-of-health (SOH) model using input data other than data provided directly by the lithium-ion cell. The input data includes at least data acquired during operation of the lithium-ion cell and/or data acquired during manufacturing and initialization of the lithium-ion cell or electrodes of the lithium-ion cell. The lithium-ion cell may be a silicon-dominant cell including a silicon-dominant anode with silicon >50% of active material of the anode, and the enhanced state-of-health (SOH) model may be configured based on one or more characteristics unique to silicon-dominant cells.
