Long-term equalization effects in Li-ion batteries due to local state of charge inhomogeneities and their impact on impedance measurements
TL;DR: In this article, a mind model is introduced to explain Li-ion battery relaxation behavior, which accounts for three equalization effects inside a particle and through an electrode layer, and two of the three effects are discussed in more detail.

Simon V. Erhard,Patrick J. Osswald,Peter Keil,Eike Höffer,Manuel Haug,Andreas Noel,Jörn Wilhelm,Bernhard Rieger,Korbinian Schmidt,Stephan Kosch,Frank M. Kindermann,Franz B. Spingler,Hauke Kloust,Torge Thoennessen,Alexander Rheinfeld,Andreas Jossen +15 more
TL;DR: In this article, a single-layer NMC/graphite pouch cell is investigated by means of differential local potential measurements during various operation scenarios and the results indicate that cell inhomogeneity is positively coupled to temperature, i.e. the lower the temperature, the more uniform the electrodes will be utilized.
Current density distribution in cylindrical Li-Ion cells during impedance measurements
Patrick J. Osswald,Simon V. Erhard,Andreas Noel,Peter Keil,Frank M. Kindermann,Harry E. Hoster,Andreas Jossen +6 more
TL;DR: In this article, modified commercial cylindrical lithium-ion cells with multiple separate current tabs are used to analyze the influence of tab pattern, frequency and temperature on electrochemical impedance spectroscopy.

Dynamics of current distribution within battery cells connected in parallel
Markus H. Hofmann,Kevin Czyrka,Martin J. Brand,Marco Steinhardt,Andreas Noel,Franz B. Spingler,Andreas Jossen +6 more
TL;DR: In this article, the authors used a linear open circuit voltage (OCV) model to simulate the current distribution of Li-ion batteries connected in parallel and found that the effect of nonlinearity in the OCV on current distribution is negligible.
