The attenuation of battery power performance results from capacity decay and impedance growth . ... ... In the battery community, empirical models are mainly used to predict the aging of the cell.
In our previous work , we found that the attenuation of battery capacity will lead to the change of electrode OCV.
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 ].
To ensure battery reliability, foreign object defect detection is commonly performed during the production and usage of batteries . Currently, there are several methods for battery defect detection: (1) Dismantling the battery to inspect internal defects . This method is costly and does not preserve the sample.
The main characteristic of battery aging is the reduction of capacity . The definition of SOH is SOH = Q M Q rated × 100% (1) where Q rated is the nominal capacity of the new battery and Q M = T 0 i (t)dt is the maximum available capacity of the aged battery. ... ...
These methods can analyze gas composition and concentration but require the internal gases of the battery to be transported to the spectrometric analysis device, which disrupts the battery's structure and potentially affects its performance.
