Abstract Lithium‐rich, manganese‐based layered oxides are considered one of the most valuable cathode materials for next generation high‐energy density lithium‐ion batteries (LIBs) their high specific capacity and low cost. However, practical implementation in LIBs is hindered by rapid voltage/capacity decay on cycling long‐standing contradictions between redox kinetics volumetric energy due to...

Lithium-ion battery (LIB) manufacturing optimization is crucial to reduce its CO2 fingerprint and cost, while improving their electrochemical performance. In this article, we present an experimentally validated calendering Discrete Element Method model for LiNi0.33Mn0.33Co0.33O2–based cathodes by considering explicitly both active material (AM) carbon-binder domain (CBD). This was coupled a pre...

Abstract A two-step framework to analyze local microstructure variations of paper sheets based on 3D image data is presented. First, a multi-stage workflow efficiently acquires large set highly resolved tomographic data, which enables—in combination with statistical analysis—the quantification and pairwise correlations morphological characteristics length scales ranging from micrometers centime...

Abstract Growth in the Li-ion battery market continues to accelerate, driven primarily by increasing need for economic energy storage electric vehicles. Electrode manufacture slurry casting is first main step cell production but much of manufacturing optimisation based on trial and error, know-how individual expertise. Advancing science that underpins electrode critical adding value chain. Over...

Abstract Micro structuring of battery electrodes with pulsed laser radiation substantially increases the performance lithium-ion batteries. For process design and monitoring, determining resulting hole diameters depths is essential. This study presents an automated, model-based approach for geometry characterization laser-drilled structures in electrodes. An iteratively re-weighted least square...

The Lithium Ion Battery electrodes microstructures and their electrochemical performance are determined by the adopted manufacturing process parameters. However, in view of strong interdependencies between these parameters, evaluating influence on is not a trivial task. In our previous publications, we have reported series computational models able to predict parameters (e.g. slurry formulation...

Potassium ion batteries (KIBs) are emerging notably due to the reversible K+ intercalation into graphite. So far, optimization of graphite electrode formulation remains, however, be investigated. This work thus proposes optimize ionic (porosity) and electronic percolation networks as well mechanical properties electrodes for KIBs. To do so, carbon black amount (CB) calendering is first adjusted...
