Introduction, material overview & electrode production
Professor Arno Kwade will go into detail about the intricate role of proper slurry mixing and dispersing of conductive additives as well as electrode coating, drying and calendering on the porous electrode structure and by extend to the electrodes properties.
Process control in electrode production
Gain insights into the utilization of advanced inline sensors in the different electrode production processes for maintaining quality and precise process control. In-line detection of intermediate product parameters during slurry mixing, electrode coating and calendering offers exciting advantages for a scaled and sustainable battery production.
Automated cell assembly
When scaling battery production to industry standards, process automation is mandatory. During cell assembly, industry-scale robotics along with cutting edge process control are key for achieving high throughputs along with adequate quality. The interplay between different grippers, transport devices, as well as camera and sensor technology ensures sufficient process stability and reproducibility.
Digitalization in battery production
Battery cell production is characterized by a large number of parameter interdependencies. Variations on a process level affect the electrode structure and, consequently, the battery cell performance. Digitization tools such as tracking and tracing and data mining enable the extraction of information from production and knowledge-based decision support. This leads to improvements in production and higher product quality, reducing scrap and resource waste.
