Project description

During this thesis, we will focus on the development of high-energy-density lithium batteries. This battery will use a metallic lithium anode generated in-situ during the first charge. The lithium metal anode will therefore not be introduced initially during the manufacture of the battery. This will greatly simplify the manufacturing process.

However, the success of this concept relies on the strict control of the first charge of the battery which depends on the electrochemical charging conditions (speed, method, and temperature). This is also strongly linked to the nature and performance of the electrolyte (Li + concentration, solvent, additive, etc.). The electrolyte will adopt a particular formulation to improve its compatibility with the lithium plating/stripping process (charge-discharge).
