New electrolytes for lithium metal batteries

New electrolytes for lithium metal batteries

This project is focused on advancing rechargeable battery technology.

This project aims to:
 

  • design new electrolytes for rechargeable batteries

  • develop a computational approach to speed up the selection of suitable electrolytes for lithium metal batteries

  • understand the key reactions occurring between the electrolyte and Li metal anode that lead to the initial solid electrolyte interphase layer formation stages.
