Abstract

Solid-state batteries (SSB) offer a promising opportunity for the EU to become an early player and enhance its position in the global battery market. Supported by a consortium comprised of key industry and academic players in the battery field, SOLVE aims to capitalize on the extensive R&D base and contribute to the scaling-up efforts required for Gen4 mass production. To this end, SOLVE will address the most significant barriers hindering sector growth by demonstrating innovations across the main stages of the value chain, optimizing active and inactive materials, and associated processing techniques under industrially relevant conditions (TRL=6). This will help achieve high-performing, cost-effective, and safe and sustainable-by-design 10-20 Ah SSB prototypes and a proof-of-concept 0.25 KWh module based on:: (i) thin, defect-free hybrid solid polymer based electrolytes (=30 µm, >0.5 mS/cm @25-40ºC, >4.7 V); (ii) high loading solid state cathodes (>4.0 mAh/cm2) based on 4V-class cathode active materials (>200 mAh/g), and (iii) ultra-thin Li metal anodes (including cutting-edge lithophilic current collectors for the development of zero Li excess SSB) (3.000 mAh/g,), all of them produced through easily scalable R2R processes. This entire process will be reinforced by the implementation of novel digital tools and models to support and accelerate the cell design process., as well as the incorporation of imperative sustainability criteria to promote efficient resource utilization through ecodesign principles and the development of innovative recycling processes. Finally, a robust dissemination, communication and exploitation strategy, including the development of tailor-made training activities and business models, will be established to propel SOLVE’s post-project commercialization and future market success, ultimately contributing to the decarbonization of the transport sector and the widespread adoption of electromobility.
