Fraunhofer R&D Center for Electromobility Bavaria SOLIDBAT - Competitive and sustainable lithium solid-state battery technology enabling large scale production for automotive application
Advancing Solid-State Batteries for Automotive Applications
The European project SOLIDBAT, funded by the European Union through its Horizon Europe program, aims to develop a disruptive technology in the field of solid-state batteries to facilitate the large-scale production for automotive application. To this end, the focus of the SOLIDBAT project is on high energy density solid-state batteries (400 Wh/kg, 1000 Wh/L), as they enable long life and increased safety, and are therefore ideally suited to meet the needs of the automotive industry.
One of the focuses of the development of this disruptive technology is to minimize the impact on the environment by reducing the use of critical raw materials, reducing the use of toxic PFAS (per- and polyfluoroalkyl substances), and developing more sustainable production processes. In this way, SOLIDBAT will contribute to the transition to climate-neutral energy and transportation, and will avoid dependence on battery production in Asian countries.
The development of the project involves innovation in five main areas:
- new digital tools and models for materials development and cell parameter design
- a nickel-rich, high-capacity, water-processable nickel-manganese-cobalt cathode material
- a 3D textured high-energy lithium metal anode coated with an artificial protective solid-electrolyte interface
- a highly conductive and electrochemically stable hybrid gel polymer electrolyte
- scalable solutions for manufacturing solid-state battery technology that easily adapt to current lithium-ion technology
