Title (EN) SERICIN-BASED BINDER FOR ELECTRODES
(FR) LIANT À BASE DE SÉRICINE POUR ÉLECTRODES
Abstract:
(EN) An electrode comprising an electroactive material and a binder dispersed in the electroactive material, wherein the binder comprises hydrolysed sericin, is provided. In particular embodiments, said electroactive material may be a high voltage cathode material comprising a spinel oxide. In various embodiments, the spinel oxide may comprise LiNi0.5Mn1.5O4 (LNMO). A method for producing the electrode is also provided.
(FR) La présente invention concerne une électrode comprenant un matériau électroactif et un liant dispersé dans le matériau électroactif, le liant comprenant de la séricine hydrolysée. Dans des modes de réalisation spécifiques, ledit matériau électroactif peut être un matériau de cathode haute tension comprenant un oxyde de spinelle. Dans divers modes de réalistion, l'oxyde spinelle peut comprendre LiNi0.5Mn1.5O4 (LNMO). L'invention concerne également un procédé de production de l'électrode.
