A Review of Lithium?Ion Battery Electrode Drying: Mechanisms and Metrology

Lithium-ion battery manufacturing chain is extremely complex with many controllable parameters especially for the drying process. These processes affect porous structure and properties of these electrode films influence final cell performance properties. However, there limited available information dynamics are poorly understood due to limitation existing metrology. There an emerging need develop new methodologies understand achieve improved quality control coatings. A comprehensive summary variables relevant wet film process presented, its consequences/effects on finished electrode/final mapped. The development mechanism critically discussed according modeling studies. Then, potential metrology techniques, either in situ or ex reviewed. This work intended perspectives application advanced techniques enable a more predictive approach identify optimum lithium-ion conditions, focus upon critical
