Multi-scale investigation of thickness changes in a commercial pouch type lithium-ion battery
Bernhard Rieger,Steffen Schlueter,Simon V. Erhard,Johannes Schmalz,Gunther Reinhart,Andreas Jossen +5 more
TL;DR: In this paper, the authors investigated the thickness change of a commercial pouch type lithium-ion battery with a graphite anode and a LiCoO 2 cathode at multiple scales.

Optimum fast charging of lithium-ion pouch cells based on local volume expansion criteria
TL;DR: In this paper, the authors explore the link between local volume expansion and lithium plating on the graphite anode of lithium-ion cells and propose a method that makes use of this link to design fast and gentle charging protocols.

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.
Multi-directional laser scanning as innovative method to detect local cell damage during fast charging of lithium-ion cells
Bernhard Rieger,Simon F. Schuster,Simon V. Erhard,Patrick J. Osswald,Alexander Rheinfeld,Christopher Willmann,Andreas Jossen +6 more
TL;DR: In this paper, Li et al. measured the thickness change of a pouch cell at multiple positions during operation and disclosed a local overshoot in thickness change during fast charging near the current collector tabs at 25°C, which significantly increases at 17°C and is not detectable at 40°C.
