Project summary description:
This research focuses on the development of innovative interfaces in next-generation solid-state batteries. Boron-rich solid-state electrolytes are exceptional ion conductors at room temperature (> 1 mS/cm) and have excellent electrochemical stability. However, attempts to successfully achieve a well performing battery have been hindered by solid-solid interface problems.

The overall aim of this project is to utilise state-of-the-art fundamental interface modification techniques to create next generation boron-based solid-state batteries. The research program differentiates itself from other studies by focusing on novel boron-based electrolytes. There is a two-prong research program that aims to i) assess the benefits of solid-state electrolyte interface modifications complimented by ii) specialised in-operando characterisation methods.
