TL;DR: In this paper, the authors compare incremental capacity and differential voltage (IC-DV) and electrochemical impedance spectroscopy (EIS) on the same data set to evaluate if both techniques provide similar insights into the causes of battery degradation.

TL;DR: In this article, a decoupled weighted recursive least squares (DWRLS) method is proposed to estimate the parameters of the battery fast and slow dynamics separately, which circumvents an additional full-order observer for battery estimation.

TL;DR: In this article, the impact of connecting cells with varied properties in parallel and the issues regarding energy imbalance and battery management that may arise was explored through analysing experimental data and a validated model, and significant differences in current flow can occur between cells within a parallel stack that will affect how the cells age and the temperature distribution within the battery assembly.

TL;DR: In this article, the authors investigated the long-term impact of current ripple on battery performance degradation and found that both capacity fade and impedance rise progressively increase as the frequency of the superimposed AC current increases.

TL;DR: In this article, the authors developed a comprehensive battery degradation model based on long-term ageing data collected from more than fifty longterm degradation experiments on commercial C6/LiNiCoAlO2 batteries.
