Plasma à pression atmosphériqueUn plasma à pression atmosphérique (ou plasma à PA ou plasma froid) est le nom donné à une catégorie spéciale de plasma pour lequel la pression approche celle de l’atmosphère.
Le plasma à pression atmosphérique marque une nette différence avec le plasma basse et haute pression. En effet, contrairement à ces derniers aucune enceinte de traitement n'est nécessaire. Ce type de plasma peut donc être utilisé directement sur ligne de production, évitant ainsi l'utilisation de vide qui est extrêmement onéreuse.

| Résumé : |
This study focuses on the vacuum-free deposition of nano-organosilicon coating through cyclonic plasma deposition on polymeric separators for application in lithium-ion batteries. Optical emission spectroscopy was used to determine various chemical plasma species and the association of the cyclonic plasma deposition of nano-organosilicon coating. The surface detections by ATR-FTIR and XPS revealed that the plasma power is the main reason affecting nano-organosilicon coating from organic to more inorganic features. The cyclonic-plasma-deposited nano-organosilicon coating was applied to the surface of a polymeric lithium-ion battery separator. The surface characteristics of the altered separator were analyzed through ATR-FTIR, TGA, EIS, and uptake test. The results indicated that the deposition of the nano-organosilicon coating on the separator surface improved the heat resistance and electrochemical performance of the polymeric separator. The synergistic effect of the cyclonic-plasma-coated separator was observed; that is, the electrolyte uptake of the cyclonic-plasma-coated separators was larger than that of a commercial separator. |
