The overall goal of the project is to perform an in-depth experimental and computational study of the solid-state lithium batteries.
The gradual move beyond conventional lithium-ion batteries seems inevitable on account of their limited energy content. Solid-state electrolytes can significantly boost the energy density as it allows for more densified cell architectures. The introduction of a solid phase to replace the conventional liquid-phase electrolytes is, however, a rather disruptive step and many material integration issues still need to be resolved. The operation of a battery relies on proper electronic and ionic contacts between the different components. The rigid nature of the solid-solid interfaces poses serious concerns about mechanical-induced degradation. Indeed, significant change of volume and insertion-induced stresses can impede decent and stable performance of a solid-state battery. Through a combination of experimental approach and macroscopic physics-based modeling, the ultimate goal of the project is to optimize the formulation and architecture of the solid-state lithium batteries.
