Customer ServiceTo identify the aging mechanism of the battery by using the OCV curve of electrodes, it is necessary to establish the correlation model between the aging and the OCV curves. Besides, considering that the SOC i of the electrode can not be measured directly, it is necessary to map the SOC of the whole battery to the electrode SOC i.
The aging mode of the battery is quantified by the capacity ratio of electrodes and the SOC bias of the positive electrode. To better understand the variation of internal parameters with battery aging, the simplified electrochemical model is used to identify the parameters in Ref. [ 24 ].
Here, the attenuation mechanism of alkaline all-iron ion flow batteries is investigated by the capacity-unbalance cells combining iron (III/II)-cyanide complexes (Fe (CN) 6) in positive electrolyte and iron (III/II)-sulfonated triethanolamine complexes (Fe (DIPSO)) in negative electrolyte.
In the beginning, the loss of delithiated material in the negative electrode only has a weak effect on the battery capacity, because the negative electrode has excessive active substances, and the OCV curve of the negative electrode remains unchanged at the low SOC stage.
Three aging modes of battery are quantified by the established OCV model. The semi-empirical models are proposed for three aging modes. The model of aging modes on ohmic/polarization resistance is established. Remaining useful life and SOH are predicted by proposed models and particle filter.
In Ref. [ 21 ], the ICA and DVA are used to qualitatively evaluate the battery aging mode, and the initial ion concentration and electrode capacity of electrodes under different cycles are identified by OCV curve fitting. However, the work did not quantify the mechanism of battery aging.
