Projektbeschreibung
Wie Festkörper-Lithiumbatterien bald nachhaltiger Energie speichern
Der europäische Grüne Deal ist das umfassende Konzept der Europäischen Kommission, mit dem Europa bis 2050 zum ersten klimaneutralen Kontinent werden soll. Das im Rahmen der Marie-Skłodowska-Curie-Maßnahmen finanzierte Projekt HOPES ist ein wichtiger Bestandteil dieses Vorhabens. Die Forschenden planen die Entwicklung nachhaltiger, kosteneffizienter Batterien, die für eine Vielzahl von Anwendungen Energie speichern können. Ziel ist die Bereitstellung inhärent sicherer, selbstheilender Festkörper-Alkalimetallbatterien, die eine bessere Alternative zu den gegenwärtig verwendeten Lithium-Ionen-Batterien darstellen. Zur Unterstützung der Einführung derartiger Batterien werden die Forschenden gemäß einem Konzept für kreislauforientierte Chemie Hybrid-Festkörperelektrolyte entwickeln.
Ziel
Threatened by climate change, mankind is facing increasing demands for energy (generation, conversion, and storage) solutions to meet societal needs in a globalized economy. Energy and cost-efficient sustainable batteries will be instrumental in reaching climate-neutral (EU) continent by 2050 and UN SDG N°7 objectives by storing intermittent energy resources and enabling a green transport revolution. To address these grand challenges, the project HOPES targets safer-by-design self-healing All-Solid-State Alkali Metal Batteries (ASSAMBs), thus implementing a paradigm shift going beyond the ubiquitous Lithium-ion Battery (LiB) technology. Taking Lithium Metal Batteries (LMBs) as a post-LiB blueprint for ASSAMBs, Solid-State Hybrid Electrolytes (SSHEs) will be developed through a circular chemistry approach to enable LMBs, facilitating their inception onto the market. Within HOPES, we will i) develop mechanically, thermally, electrochemically tough self-healable and recyclable SSHEs through the colloidal self-assembly of nanosized building blocks consisting of inorganic core and end-group (vitrimer functionality)-functionalized Li+ conducting polycarbonate shell: Hairy NanoParticles (HNPs), and ii) establish multi-scale structure/property correlations with advanced characterization techniques at HNP, SSHE, and LMB levels, including synchrotron-based in situ and operando characterizations on operating LMBs. Depolymerization of HNP’s organic shell will trigger the disassembly of SSHEs, thereby authorizing the recovery & reuse of inorganic NP cores and (bio-based/sourced) cyclocarbonate monomers, but also the recycling & reuse of (NMC811) cathode and Li° anode to secure critical/strategic minerals and metals in EU. In line with roadmaps of the FET-Flagship Battery 2030+ initiative & EBA250, HOPES will act as a springboard to realize ambitions and objectives of the EU Green Deal, thus contributing to position EU as a major research player and battery manufacturer by 2030.
