Summary
Electrode manufacturing for lithium-ion batteries is a complex, multistep process that requires comprehensive material characterization to ensure quality and consistency in the final electrodes. Electrode processing involves combining active materials with binders and conductive additives to form a coating on the current collector, either as a slurry or dry coating. The mixing and coating process exposes these materials to a range of different shear environments that may affect their final performance.
Rheology offers crucial measurements for optimizing both slurry processing and dry electrode, including slurry flow properties, powder flow and powder cohesion. Rheological data can predict how formulations and processing affect the final electrode’s structure and heterogeneity, ensuring successful performance.
By watching this webinar, you will learn:
- Rheology basics for materials characterization in battery electrode manufacturing
- How to optimize battery electrode manufacturing through comprehensive material and slurry characterization
- The impact of critical powder and slurry properties on processability, including transport, mixing, and coating
- How to assess raw materials’ and processing’s effects on electrode structure and heterogeneity
