Glass-ceramic electrolytes for high performance solid-state batteries
Lithium-ion batteries have become the primary choice for rechargeable batteries in portable electronics and the transportation sector. Solid-state batteries are predicted to be the next generation batteries that will solve limitations and problems with today's Li-ion batteries, such as fire risk, energy density, temperature range, and lifetime.
The project aims to develop new types of sulfur-based glass-ceramic electrolytes and test them in solid-state batteries. Projects will address many challenges such as incompatibility and instability in relation to the electrode materials. A combination of glass-ceramic electrolyte development and state-of-the-art interface characterization techniques developed at Uppsala University's - Ångström Advanced Battery Center will be used. Solid-state battery cells manufactured in so-called "pouch cells" on a lab scale are the final product, which has a goal of having an energy density of 500 Wh/kg and is tested at 30 °C and 60 °C. This is crucial for practical high-performance solid-state batteries to be based on these electrolytes.
