Advanced materials and cells development enabling large-scale production of Gen4 solid-state batteries for mobility applications (Batt4EU Partnership)

Proposals are expected to cover all the following points:

• Develop or leverage the materials-specific models and digital tools for material and cell design to identify the best combinations of materials and speed up the cell optimisation process.
• Ensure high ionic conductivity (> 0.5mS/cm²) and stability of the solid electrolyte.
• Integrate high voltage cathode (> 4V) to reach the KPIs for mobility as listed in the Expected Outcomes section.
• Propose and evaluate interfaces and coating solutions especially to suppress dendrite growth and enable a stable solid-electrolyte interphase (SEI) and cathode-electrolyte interphase (CEI).
• Optimise the cell design with respect to all the cell components to meet high energy density objectives.
• Anode current collectors and/or solid electrolyte capable of accommodating volume changes upon charge/discharge.
• Demonstrate the potential for scale up of materials, cells and sustainable industrial processing methods with cells reaching a capacity of several Ah, produced in a statistical meaningful number to demonstrate the process repeatability.
• Project publications should adhere to the guidelines for publication of research results, as laid out by the ""Batteries Europe - Reporting Methodologies"" report, subject to the need to maintain confidentiality for future commercial exploitation.

Plans for the exploitation and dissemination of results for proposals submitted under this topic should include a strong business case and sound exploitation strategy, as outlined in the introduction to this Destination. The exploitation plans should include preliminary plans for scalability, commercialisation, and deployment (feasibility study, business plan) indicating the possible funding sources to be potentially used (in particular the Innovation Fund).

Projects should link to ongoing Horizon Europe calls, especially HORIZON-CL5-2021-D2-01-03: Advanced high-performance Generation 4a, 4b (solid-state) Li-ion batteries supporting electro mobility and other applications and HORIZON_CL5-2021-D1-01-05 (Manufacturing technology development for solid-state batteries (SSB, Generations 4a - 4b batteries). Projects should also take stock of the outcomes of the projects under call LC-BAT-1-2019 (Strongly improved, highly performant ad safe all-solid-state batteries for electric vehicles).

This topic implements the co-programmed European Partnership on Batteries (Batt4EU). As such, projects resulting from this topic will be expected to report on the results to the European Partnership on Batteries (Batt4EU) in support of the monitoring of its KPIs.
