Batteries lithium-ion (LIB).<\/span><\/h5>

La transition \u00e9nerg\u00e9tique<\/strong> entra\u00eene une croissance exponentielle des ventes de v\u00e9hicules \u00e9lectriques (VE). La principale chimie de cathode des batteries lithium-ion (LIB) pour 2025 repose sur les compos\u00e9s LiNix<\/sub>Mny<\/sub>Coz<\/sub>O\u2082 (NMC).<\/p>

La demande en lithium (Li) et en cobalt (Co) devrait \u00eatre multipli\u00e9e respectivement par 15 et par 60 d\u2019ici 2030.<\/strong><\/p>

Recyclage des m\u00e9taux issus des LIB.<\/strong><\/span><\/h5>

Les principales m\u00e9thodes de recyclage des m\u00e9taux contenus dans les \u00e9lectrodes des LIB sont essentiellement des proc\u00e9d\u00e9s pyro- et hydrom\u00e9tallurgiques. Cependant, la pyrom\u00e9tallurgie est \u00e9nergivore<\/strong>, \u00e9met des gaz toxiques<\/strong> et le lithium est perdu<\/strong> dans les scories, tandis que l\u2019hydrom\u00e9tallurgie g\u00e9n\u00e8re de grandes quantit\u00e9s d\u2019effluents organiques toxiques<\/strong> et d\u2019effluents aqueux acides<\/strong>.<\/p>

\u00a0Il est donc n\u00e9cessaire<\/strong> de d\u00e9velopper des proc\u00e9d\u00e9s de recyclage alternatifs plus respectueux de l\u2019environnement<\/strong>.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

Le projet POLYCRICRI se distingue par son approche innovante<\/strong> allant bien au-del\u00e0 de l\u2019utilisation du CO\u2082 comme simple fluide d\u2019extraction supercritique. Il ambitionne, pour la premi\u00e8re fois, de d\u00e9velopper et d\u2019\u00e9tudier de mani\u00e8re int\u00e9gr\u00e9e un proc\u00e9d\u00e9 \u00ab tout-en-un \u00bb permettant la lixiviation, la complexation s\u00e9lective et la solvatation des m\u00e9taux contenus dans les mat\u00e9riaux de cathode de batteries lithium-ion<\/strong> (LIB), au moyen d\u2019agents extractants macromol\u00e9culaires sp\u00e9cifiquement con\u00e7us, op\u00e9rant dans des conditions s\u00e8ches ou quasi s\u00e8ches. Par ailleurs, une attention particuli\u00e8re est accord\u00e9e au d\u00e9veloppement et \u00e0 l\u2019utilisation de polym\u00e8res exempts de PFAS (compos\u00e9s per- et polyfluoroalkyl\u00e9s),<\/strong>\u00a0ce qui repr\u00e9sente un d\u00e9fi scientifique et technologique majeur dans le contexte du CO\u2082 supercritique.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
