Effect of PVdF distribution on properties and performance of dry spray-coated graphite electrodes for lithium-ion batteries for electric vehicle applications

Résumé

We used electrostatic dry spray-coating to fabricate graphite/PVdF anodes. We compared the morphological, mechanical, electrical, and electrochemical properties of electrodes fabricated with three different mixing times of dry electrode components. Quantitative and novel relationships between the PVdF distribution and the electrode properties were obtained. Our investigations suggest that our fabrication methods are viable alternatives for producing electrodes with comparable properties to those fabricated using traditional wet solvent-based methods. Overall, our work provides insights into new and promising methods for fabricating high-quality dry-sprayed electrodes (DSEs) with high mass loadings for use in a variety of electrochemical applications such as electric vehicles.
