Generate a local EU industry that revolves around a cost-effective, robust all-solid-state Li battery comprising sustainable materials by 2026.
SEATBELT intends to achieve the first technological milestone of developing a battery cell (TRL5) meeting the needs of Electric Vehicle (EV) and stationary industry.
A disruptive solid-state battery cell :
Low-cost safe-by-design cell with sustainable and recyclable materials, reaching high energy densities (>380 Wh/kg) and long cyclability (>500 cycles) by 2026 in line with the 2030 EU targets.
Cells produced by low-cost solvent-free extrusion process comprising a combination of innovative materials: Li metal, hybrid electrolyte, safe cathode active material.
Design optimization by interface (operando and atomistic modelling) and process (machine learning) methodologies.
New in situ imaging instrumentation will be developed to investigate safety properties and mechanical deformation to assess cell safety in real conditions.
An innovative recycling cycle from materials to cell level will be established.
Consortium :
SEATBELT will be the start point of a first EU all-solid-state battery value chain, whose main players in RTD and Industry sectors are within the consortium.
