Description du projet
L’impression 3D pour des batteries au lithium plus sûres et moins chères
Par rapport aux autres technologies, les batteries lithium-ion (LIB) sont encore relativement nouvelles dans le domaine du stockage d’énergie. Très utilisées en électronique, elles sont rechargeables et possèdent une densité énergétique élevée. Il existe une demande croissante pour des LIB plus sûres, plus fiables et plus abordables. Pour répondre à ce besoin pressant, la technologie de l’impression 3D s’impose comme la solution la plus viable. Le projet 3D-PRESS, financé par l’UE, développera une technologie d’impression 3D dans le cadre de la production de LIB à l’état solide, et en fera la promotion. Le projet proposera de nouveaux matériaux imprimables qui faciliteront la croissance de la production de LIB entièrement solides et intégralement imprimables en 3D.
Objectif
The main goal of the 3D-PRESS project is to advance in the 3D printing concepts for safer, cheaper and customizable all-solid state Li-ion batteries (LIB). More specifically, the project is focused on the design, production, characterization and testing of 3D printed NASICON-type glass-based electrolytes for 3D printed batteries.
In 3D-PRESS, glass-based compositions will be designed and synthesized in order to obtain printable glass-based electrolytes with superior conductivity and functional properties. The produced glasses will be thermally and electrochemically characterized in order to investigate their sinter-crystallization behaviour (tailoring suitable sintering treatments) and electrochemical performances. The most promising electrolyte compositions will be selected to be printed in free-form robust self-standing structures in order to obtain 3D batteries with high active area (allowing high specific energy and power per unit volume).
3D-PRESS represents a cutting edge multidisciplinary approach for the development of reliable and customizable all-solid state 3D LIBs, especially interesting for micro-power applications such as the ones for Internet of Things (IoT). The project will provide a new family of printable materials increasing the short list of available compositions, especially solid electrolytes, opening the door to the development of a new generation of fully printable all-solid state 3D LIBs.
A high impact on the future career of the candidate is expected by complementing his current background with new skills in one of the more relevant Key Enabling Technologies (KETs), 3D-printing, applied to the crucial field of the Energy Storage. Moreover, the host institute will offer unique opportunities to re-enforce the technology transfer competences of the candidate by carrying out an industrial secondment and by the involvement in the KIC Innoenergy community.
