STAGE : Mise en forme d’adsorbants pour la capture directe de lithium (FRA)
Lieu du Stage : Institut de Chimie et des Matériaux Paris-Est (ICMPE)
Laboratoire, équipe d’accueil et encadrants :
- Institut de Chimie et des Matériaux Paris-Est (ICMPE) – UMR 7182 CNRS – Université Paris-Est Créteil
2, rue Henri Dunant – 94320 Thiais
Dr B. Le Droumaguet, Maître de Conférence, benjamin.le-droumaguet@cnrs.fr - Geolith, 1 rue Jean Rostand – 91400 Orsay
Dr Guillaume Gros, Responsable scientifique, ggros@geolith.com
Début : février-mars 2025; 5-6 mois
Contexte et problématique :
Dans le contexte actuel de transition énergétique, GEOLITH vise à sécuriser un approvisionnement durable de lithium, élément critique pour la fabrication de batterie. GEOLITH a mis au point un procédé et matériau innovant permettant d’extraire le lithium contenu dans diverses saumures, dont notamment les saumures issues de la géothermie et du domaine du recyclage de batterie. Dans l’optique d’optimiser le matériau et de diversifier les possibilités de fluides à traiter, GEOLITH souhaite mettre en forme son matériau sous forme d’un matériau hydride polymère poreux – particules inorganiques. Le stage proposé s’inscrit directement dans cette démarche.
Les tâches de ce travail sont les suivantes :
- Mettre aux point un matériau hydride polymère – particules inorganique poreux et le caractériser (porosité, composition chimique) au moyen de diverses techniques présentes au laboratoire
- Tester la résistance chimique et mécanique des matériaux formés, notamment face aux conditions expérimentales utilisées pour la régénération des matériaux hybrides
- Tester les matériaux prometteurs pour l’extraction directe de lithium sur des solutions modèles chargées en ions lithium (capacité de capture, sélectivité, cyclage)
Profil :
Etudiant.e en Master 2 ou formation équivalente ayant des compétences en chimie des polymères et/ou des matériaux. Des compétences en adsorption et/ou en céramiques seraient un plus. Elle/il devra être sérieux, méthodique, autonome, faire preuve d’un savoir-faire expérimental et d’un attrait pour la recherche. Au cours de ce stage, un séjour sur le site de GEOLITH est envisagé.
Pour candidater, merci d’envoyer un CV et une lettre de motivation aux deux encadrants mentionnés

Team play
By joining our team, you might find yourself witnessing some intense foosball and pool matches.
They work at Geolith
“As a member of the GEOLITH Research & Development team since October 2020, I’m involved in several missions, such as conducting experiments to optimise and develop our technology and carrying out preliminary studies for our prospects and customers to determine the viability of our solutions.
GEOLITH recently put me in charge of managing the laboratory to make working conditions easier for the members of the R&D team.
What motivates me every day at GEOLITH is to be part of a project whose advances are helping to create a more sustainable future, to work closely with all the teams, and to see GEOLITH’s constant progress towards its position as a pioneer in direct lithium extraction.”
Head of laboratory
“I joined GEOLITH three years ago as a trainee design draughtsman at the Orsay site. After a rewarding year, I was offered the opportunity to join the GEOLITH site in Alsace to pursue my master’s in industrial design and Ergonomics (GICE).
GEOLITH provided me with an ideal environment in which to develop both personally and technically, by discovering lithium extraction methods through innovative pilot projects. Today, with my engineering degree validated, I’m proud to hold the position of engineer in the design office at GEOLITH.
My main role is to develop, design and implement lithium extraction processes. My three years at GEOLITH have given me a wealth of experience and valuable expertise, enabling me to make an active contribution to the company’s innovations and progress in this critical area of activity.”
Apprentice Design Engineer
“Working at GEOLITH provides the opportunity to grow in a truly innovative and rapidly expanding industry that is helping to shape the world of tomorrow. Lithium supply is a major challenge, not only for our clients from various industries but also on a geopolitical level, making the commercial role both diverse and exciting.
GEOLITH is at a pivotal moment in its development, on the brink of its industrialization process, and being part of this journey offers a unique experience.”
