Process modeling of the electrode calendering of lithium-ion batteries regarding variation of cathode active materials and mass loadings
TL;DR: In this paper, a Heckel-based model equation is supplemented by a predictive model for the lowest achievable coating porosity based on the theoretical packing structures of equally sized spheres.

Correct water content measuring of lithium-ion battery components and the impact of calendering via Karl-Fischer titration
TL;DR: In this paper , the effect of coating compaction due to calendering on the moisture content of anode and cathode material is investigated and the results can be helpful for a better understanding of possible sources of water contamination and process design for electrode production.

TL;DR: Sure, here is the TLDR for the provided text:
Titration techniques are used to quantify LiOH and Li2CO3 on the surface of NCM811 cathode active materials. The presence of these surface species leads to Li leaching and capacity loss. The optimized titration techniques enable accurate determination of small quantities of surface carbonate or hydroxide, providing valuable information for predicting battery performance and controlling material quality.
Diagnosis tools for humidity-born surface contaminants on Li[Ni0.8Mn0.1Co0.1]O2 cathode materials for lithium batteries
Annika Regitta Schuer,Matthias Kuenzel,Shuo Yang,Malte Kosfeld,F.M. Mueller,Stefano Passerini,Dominic Bresser +6 more
TL;DR: In this article , a diagnostic set of tools to rapidly assess the extent of surface contaminants on Ni-rich NMC materials comprising different titration methods, electron microscopy, and the determination of the reversible and irreversible water adsorption is presented.
