Title

(EN) ELECTROCHEMICAL ELECTRODES FABRICATED FROM A POLYMER PRECURSOR MATERIAL AND A METHOD AND A SYSTEM FOR FABRICATING ELECTROCHEMICAL ELECTRODES USING A DEEP DEFOCUSED LASER

(FR) ÉLECTRODES ÉLECTROCHIMIQUES FABRIQUÉES À PARTIR D'UN MATÉRIAU POLYMÈRE PRÉCURSEUR, PROCÉDÉ ET SYSTÈME DE FABRICATION D'ÉLECTRODES ÉLECTROCHIMIQUES À L'AIDE D'UN LASER DÉFOCALISÉ PROFOND

Abstract

(EN) There is provided a system, method, and electrochemical electrodes fabricated from a polymer precursor material. Fabrication of the electrochemical electrodes includes applying a defocused laser pulse by a laser to a micro-scale area of the polymer precursor material, the laser positioned at a defocused distance relative to the polymer precursor material; and repeatedly, until a predetermined pattern is generated: moving the laser or the polymer precursor material; and subsequently or concurrently applying the defocused laser pulse to further micro-scale areas of the polymer precursor material, wherein the polymer precursor material with the predetermined pattern applied forms the electrochemical electrodes.

(FR) L'invention concerne un système, un procédé et des électrodes électrochimiques fabriquées à partir d'un matériau polymère précurseur. La fabrication des électrodes électrochimiques comprend les étapes consistant à appliquer une impulsion laser défocalisée par un laser à une zone à l'échelle micrométrique du matériau polymère précurseur, le laser étant positionné à une distance défocalisée par rapport au matériau polymère précurseur ; et répéter, jusqu'à l'obtention d'un motif prédéfini : déplacer le laser ou le matériau polymère précurseur ; et appliquer, ensuite ou simultanément, une impulsion laser défocalisée à d'autres zones à l'échelle micrométrique du matériau polymère précurseur, le matériau polymère précurseur ayant le motif prédéfini appliqué formant les électrodes électrochimiques.
