Comprehensive Rheological Characterization to Optimize Electrode Manufacturing

From TA Instruments Jun 11 2024

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.
