This paper focuses on the issue of lifetime prognostics and degradation prediction for lithium-ion battery packs. Generally, health prognostic and lifetime prediction for lithium-ion batteries can be divided into model-based, data-driven, and hybrid methods .
Lithium battery degradation is the gradual aging throughout its lifespan. It typically involves chemical and physical changes to the electrolyte and electrodes, such as decomposition, dissolution, or film growth. The degradation can also be slow or fast, depending on the severity of the contributing factors.
Lithium-ion batteries unavoidably degrade over time, beginning from the very first charge and continuing thereafter. However, while lithium-ion battery degradation is unavoidable, it is not unalterable. Rather, the rate at which lithium-ion batteries degrade during each cycle can vary significantly depending on the operating conditions.
Consumption of the cell’s lithium ions through SEI growth is one contributing factor to the degradation mode known as loss of lithium inventory (LLI). Because these reactions occur even when the cell is not in use, known as calendar aging, lithium-ion battery degradation is unavoidable.
Cycling-based degradation The cycle of charging and discharging plays a large role in lithium-ion battery degradation, since the act of charging and discharging accelerates SEI growth and LLI beyond the rate at which it would occur in a cell that only experiences calendar aging. This is called cycling-based degradation.
Generally, health prognostic and lifetime prediction for lithium-ion batteries can be divided into model-based, data-driven, and hybrid methods . One type of model-based method is based on empirical or semi-empirical models of the degradation curve under specific aging conditions.
