European SOLiDIFY Project Develops Advanced Lithium-Metal Solid-State Battery for Electric Vehicles

(IN BRIEF) The SOLiDIFY consortium, part of the Horizon 2020 initiative, has developed a high-performance lithium-metal solid-state battery with an energy density of 1070 Wh/L, surpassing current lithium-ion batteries. This innovative “liquid-to-solid” electrolyte battery, produced at Belgium’s EnergyVille lab, offers improved safety, efficiency, and affordability for electric vehicles. The battery’s production process is compatible with existing lithium-ion lines and is projected to cost under €150 per kWh, paving the way for sustainable, scalable battery solutions in electromobility.

(PRESS RELEASE) DÜBENDORF, 14-Sep-2024 — /EuropaWire/ — The Horizon 2020 SOLiDIFY consortium, made up of 14 European partners, has successfully developed a high-performance lithium-metal solid-state battery. Manufactured in Belgium’s EnergyVille lab, the battery features an innovative “liquid-to-solid” processed electrolyte, providing an energy density of 1070 Wh/L—significantly higher than current lithium-ion batteries. The prototype is designed for electric vehicle applications, offering greater energy efficiency, safety, and affordability.

This breakthrough manufacturing process, adaptable to existing lithium-ion production lines, is projected to cost less than €150 per kWh, opening the door to commercially viable solid-state batteries. The battery also uses cobalt-lean materials, reducing environmental impact while enhancing performance. The consortium’s next steps include upscaling this technology to bring it closer to industrial applications and further support Europe’s push toward sustainable mobility.

SOLiDIFY H2020

The SOLiDIFY H2020 project comprised the development of a manufacturable solid-state lithium-metal battery technology based on a unique liquid-to-solid processed solid electrolyte which is impregnated into the electrodes providing multiple advantages towards cell performance and upscale manufacturing both directly in relation with the cost of cell. The SOLiDIFY consortium consisted of research centers imec/EnergyVille (Belgium), Fraunhofer (Germany), Centro Ricerche Fiat SCPA (Italy), and Empa (Switzerland), Hasselt University/EnergyVille (Belgium) and Delft University of Technology (The Netherlands); as well as industry partners VDL Groep (The Netherlands), Umicore (Belgium), Solith (Italy), SOLVIONIC (France), Sidrabe (Latvia), Leclanché (Switzerland), Gemmate Technologies (Italy) and Powall (The Netherlands). The project has received funding from the EU’s Horizon 2020 research and innovation program and was coordinated by imec. Further information on the project can be found at www.solidify-h2020.eu.
