MultiBat: Multiscale Modeling of Glassy Electrolytes for Solid-State Batteries

Solid-state batteries (SSBs) are an advanced type of battery technology that uses solid electrolytes instead of the liquid or gel electrolytes found in traditional lithium-ion batteries. SSBs exhibit higher energy density, improved safety and longer lifespan, making them ideal for applications like electric vehicles and consumer electronics. However, using solid-state electrolytes with a disordered structure – so-called glassy electrolytes – in SSBs still requires some fine-tuning. Funded by the Marie Skłodowska-Curie Actions programme, the MultiBat project aims to address challenges associated with brittle fracture and scalability in production of glassy electrolytes. Researchers will employ multiscale and multiphysics modeling to understand how glassy electrolytes behave at different scales and to unveil material properties. The work is expected to enhance the safety and efficacy of SSBs.
