Battery aging mechanisms under different charging stresses are identified. When less than 1C, Charging current is the deciding factor of active material loss. When less than 4.2 V, Cut-off voltage is the deciding factor of lithium loss. A capacity degradation rate model at different aging states is established.
Furthermore, battery aging mechanisms at various charging currents and cut-off voltages are investigated using incremental capacity analysis. It is indicated that charging current and cut-off voltage should be reduced to retard battery degradation when the battery degrades to a certain extent.
Indeed, the unavailability of battery aging discharge data in most real-world applications makes the State of Health (SoH) assessment very challenging. Alternatively, accelerated aging is therefore adopted to emulate the degradation process and to achieve an SoH estimate.
However, after the battery suffers a certain number of cycles at 1C and 4.2 V, the charge acceptance capability of the battery gets weak, and as a result, the LAM and LLI will accelerate. So, reducing charging stresses in an appropriate aging stage is necessary to delay battery aging.
Among others, it is conceivable to use the battery aging dataset to derive degradation models based on semi-empirical or machine-learning approaches or to use the raw cycling data to test and validate SoC or cell impedance estimators.
