Text of Abstract
Both shear and extensional rheology are critical to the battery manufacturing process as they dictate the slurry processibility and the structure achieved in the coated thin film. The porous cathodes of LIBs are a composite of micron-sized electrochemically AM (active material) particles, nanometer-scale conductive additive CB (carbon black), and polymer binder PVDF (poly(vinylidene difluoride)).
