The importance of slurry rheology in battery electrode development and manufacturing scale-up.

Slurry rheology and the scale-up challenge for cell manufacturers
Producing a quality coating requires more than good equipment and operator skill. It begins with controlling slurry quality as a critical process input.
That’s the premise of a recent article published in the Q2 edition of Converting Quarterly, as part of their Special Market Report on R2R battery manufacturing. The piece covers how electrode slurry rheology drives coating window definition, influences coat weight uniformity, and needs to be carried forward deliberately through each stage of electrode development — from lab to pilot to full production.
Analytical Solutions for Battery Material Characterization
TA Instruments Seminar — University of Michigan Battery Lab, July 15th
BJ Kays is presenting at a one-day seminar hosted by TA Instruments at the University of Michigan EECS building in Ann Arbor on July 15th. The event runs 9:00 a.m. to 4:45 p.m. and is free to attend — lunch is included.
BJ’s talk is titled From Lab to Gigafactory: Rheology as a Process Design Input for Battery Electrode Coating and is scheduled for 2:15–3:15 p.m. It covers why single-point viscosity measurements fall short, how full rheological characterization informs slot die design and operating window selection, and why batch-to-batch variation is among the most common sources of scrap in production.
Agenda:
8:30 – 9:00 AM Continental Breakfast
9:00 – 9:30 AM Introduction to the UM Battery Lab — Greg Less
9:30 – 10:30 AM Thermal Analysis for Battery Material Characterization
