self-assembled/healable Hybrid inorganic/Organic Polymer Electrolytes for sustainable electrochemical energy Storage
In the field of electrochemical energy storage, researchers are actively pursuing safer and higher energy density alternatives to traditional Lithium-ion batteries (LiBs). The imperative to facilitate electric mobility and contribute to UN Sustainable Development Goal #7 drives this quest. All-solid-state batteries (ASSBs) have emerged as a focal point of research interest over the past decade. However, challenges persist in realizing the market introduction of this transformative energy storage technology. However, challenges persist in realizing the market introduction of this transformative energy storage technology. Key among these challenges is the fabrication of inorganic, organic, or hybrid (inorganic/organic) solid-state electrolytes (SSEs) characterized by broad electrochemical stability windows (ESWs), high ionic conductivity values, and chemical resistance to alkali metals (e.g., Li°). Solid Inorganic Electrolytes (SIEs): These demonstrate high ionic conductivity and extended ESW but face challenges related to thermal processing and scalability. Salt-in-Polymer Solid Polymer Electrolytes (SiP-SPEs): Easier to synthesize, but they exhibit lower ionic conductivity and a narrower stability window. Single-Ion SPEs (SISPEs): Promising cation transference numbers but limited overall conductivity. Solid Composite Electrolytes (SCEs): These combine active and passive fillers, aiming to merge desirable features. The MSCA-IF project titled “Self-assembled/Healable Hybrid Inorganic/Organic Polymer Electrolyte for Electrochemical Energy Storage” (HOPES) aligns with EU initiatives. It targets high-performance, sustainable all-solid-state lithium metal batteries (LMBs). HOPES aims to overcome scientific and technological obstacles hindering the realization of ultra-performing ASSBs. Specific objectives include developing robust, self-healable, and recyclable SSEs through colloidal self-assembly of nanosized building blocks (known as Hairy NPs or HNPs). Additionally, the project seeks to establish structure-property correlations using advanced characterization techniques at various levels, including synchrotron-based characterizations. This ambitious initiative holds the promise of advancing the frontiers of solid-state battery technology, ensuring safety, high performance, and sustainability.

Project objective
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.
