Abstract:
(EN) In order to improve the linearity of lithium ions in a high loading electrode, a method for manufacturing an electrode having a path by inputting and mixing amorphous selenium nanoparticles together into a process for making the existing electrode slurry of mixing an electrode active material, a conductive material, and a binder and then after coating with the electrode slurry by vaporizing selenium nanoparticles during drying. The method for manufacturing an electrode for a secondary battery comprises: a step of preparing binder solution by dispersing or dissolving the binder in a solvent; a step of preparing an electrode slurry by mixing the binder solution with an electrode material comprising an electrode active material, a conductive material, and amorphous selenium nanoparticles; a step of coating the electrode slurry on a current collector; and a step of vaporizing the amorphous selenium nanoparticles while drying the coating to foam the coating layer.
(FR) La présente invention a pour objet d'améliorer la linéarité d'ions lithium dans une électrode à charge élevée. À cette fin, la présente invention concerne un procédé permettant de fabriquer une électrode ayant un trajet en introduisant et en mélangeant des nanoparticules de sélénium amorphe ensemble dans un processus permettant de fabriquer la suspension d'électrode existante de mélange d'un matériau actif d'électrode, d'un matériau conducteur et d'un liant, et, ensuite, après le revêtement avec la suspension d'électrode par vaporisation de nanoparticules de sélénium pendant le séchage. Le procédé permettant de fabriquer une électrode pour une batterie rechargeable comprend : une étape consistant à préparer une solution de liant par dispersion ou dissolution du liant dans un solvant; une étape consistant à préparer une suspension d'électrode par mélange de la solution de liant avec un matériau d'électrode comprenant un matériau actif d'électrode, un matériau conducteur, et des nanoparticules de sélénium amorphe; une étape consistant à recouvrir la suspension d'électrode sur un collecteur de courant; et une étape consistant à vaporiser les nanoparticules de sélénium amorphe tout en séchant le revêtement pour mousser la couche de revêtement.
