Next generation of solid-state lithium batteries electrolytes

Rechargeable lithium-ion batteries have revolutionized the portable electronics industry because of their high energy density and efficiency. They may also prove valuable for a variety of other applications, including electrification of the transport system and grid-scale stationary energy storage. However, they still suffer from several significant safety and reliability issues, many of which are related to the use of electrolytes dissolved in organic solvent. Solid-state electrolytes could resolve all of these problems. However, most candidate materials have much lower ionic conductivity compared to that of liquid electrolytes, which reduces the power density of the cell and limits their practical applications.

Prussian Blue analogues have recently demonstrated remarkable electrochemical performance that is enabled by rapid movement of ions through their open-framework crystal structure. 

The overarching goal of this project is to identify PBAs materials that function as a stable, high-power solid electrolyte for lithium-ion batteries. PBA materials have many tunable properties that affect their electronic and structural characteristics. In this project, the student will explore the effect of these parameters on the structural, electronic and electrochemical properties of PBA. Collaborations (both internal, external) are expected.
