Battery aging impedance spectroscopy and incremental capacity analysis [PDF]
, 2017 We analize electrochemical LiFePO4 cells with impedance spectroscopy and incremental capacity analysis in order to establish a correlation with capacity fade. We found that polarization and diffusion impeances increased with aging, but at different rates

Online Diagnosis for the Capacity Fade Fault of a Parallel-Connected Lithium Ion Battery Group
Energies, 2016 In a parallel-connected battery group (PCBG), capacity degradation is usually caused by the inconsistency between a faulty cell and other normal cells, and the inconsistency occurs due to two potential causes: an aging inconsistency fault or a loose ...
