Coating Matters Episode 95: Why Electrode Coating is the Limiting Factor

Written By BJ Kays

Coating Matters host Mark Miller is joined by BJ Kays of Coating Edge Solutions to discuss slot die coating in the battery industry. While the industry debates chemistries (NMC vs LFP, wet vs dry, silicon-content, solid-state, and more) the current real limiter to the U.S and EU battery scale-up is the lack of precision and control in electrode manufacturing. Coating uniformity, flow behavior, slurry design, and the die setup create the majority of yield loss, throughput limits, and ramp up failures.
