| Abstract Scope |
Solid electrolytes are a critical component of all-solid-state batteries (ASSBs). However, achieving high ionic conductivities and wide electrochemical windows simultaneously has been a challenge for decades. In this investigation, we studied a new class of Li-glass electrolytes based on Li2.99Ba0.005OCl. The dependance of the ionic conductivity of Li2.99Ba0.005OCl electrolyte on the synthesis condition and the degree of amorphous and crystalline components in the Li-rich anti-perovskite Li2.99Ba0.005OCl were studied. Furthermore, several methods for fabricating standalone Li-glass electrolyte membranes were investigated. It was found that the ionic conductivity of Li-glass electrolyte can be very high, ranging from 10-3 to 10-4 S/cm at room temperature depending on the synthesis condition. Standalone Li-glass electrolyte membranes can be fabricated with non-polar solvents and binders. The challenges in synthesizing Li2.99Ba0.005OCl electrolyte and fabricating its membranes as well as their implications for ASSBs will be discussed in this presentation. |
