Extrusion tests for electrode paste

Approach

1. Site visit to inspect the equipment at the pilot plant and to plan in detail the execution of the tests.
2. Kick-off and definition of further project objectives and expectations.
3. Provide a suitable formulation, material selection, and preparation at KraussMaffei Technical Centre.
4. Procurement, preparation, and packaging of raw materials and measuring equipment for analysis.
5. Perform the tests, evaluate the results, and make recommendations for action.
6. Running the test series and providing on-site operational support during the tests. 
7. Sampling and analysis with subsequent reporting and recommendations for action.

Results

The partner in the project received an introduction to lithium-ion battery technology, covering its operation, components, cell formats, characteristics, and value chains. The seminar also explored the present market landscape, including the manufacturers, consumers, location factors, market size, growth, and cost structure. In addition, it provided an understanding of the complete manufacturing process of lithium-ion battery cells, from electrode production to cell assembly and refinement, as well as the components of battery modules and packs. Following the battery value chain, we gave also a glimpse into future battery and battery manufacturing technologies, as well as second-life and battery recycling.

After that, we defined the objectives for extrusion testing. In addition, the details and specifics of the extruders were discussed in detail and documented. The extrusion tests were carried out and the results were carefully documented. Based on the successful extrusion tests, which met the requirements for electrode paste production, the final report is now being prepared. This report will contain the detailed results and conclusions of the trials and provide an assessment of the performance of the extrusion process.
