Experimental Investigation of the Temperature, Pressure, and Binder System Influence on Vacuum Postdrying Processes and Moisture Management of Li‐Ion Battery Electrodes

Moisture management and postdrying are crucial for Li‐ion battery lifetime performance as well overall energy efficiency of electrode production. An optimization these processes by a fundamental comprehension sorption mass transport mechanisms in the holds potential to increase sustainability this technology. The composition electrodes determines which govern interaction with water from atmosphere. In study, influence binder system, temperature, pressure anodes on is focused on. Anodes system carboxymethylcellulose (CMC)/styrene–butadiene–rubber (SBR) polyvinylidene fluoride represent mostly absorbing adsorbing material respectively. Variation process parameters temperature reveals that both systems show similar impact during removal, although reduced CMC/SBR expected, since case most absorbed into polymers should diffuse independently pressure. Temperature affects stronger than due strong dependency diffusion inside polymers.
