Title
(EN) ELECTRODE FORMULATION FOR LI-ION BATTERY AND METHOD FOR PRODUCING AN ELECTRODE BY EXTRUSION AT LOW RESIDENCE TIME
(FR) FORMULATION D'ÉLECTRODE POUR BATTERIE LI-ION ET PROCÉDÉ DE FABRICATION D'ÉLECTRODE PAR EXTRUSION A FAIBLE TEMPS DE SÉJOUR
Abstract
(EN)
The invention relates to an electrode formulation for a Li-ion battery. The invention also relates to a method for preparing electrodes using said formulation by compounding/extrusion at low residence time. The invention further relates to an electrode obtained by this method and to secondary Li-ion batteries comprising at least one such electrode.
(FR)
L'invention concerne une formulation d'électrode pour batterie Li-ion. L'invention concerne aussi un procédé de préparation d'électrodes mettant en œuvre ladite formulation, par compoundage/extrusion à faible temps de séjour. L'invention se rapporte enfin à une électrode obtenue par ce procédé ainsi qu'aux batteries secondaires Li-ion comprenant au moins une telle électrode.
