Study of the electrode/electrolytes interfaces in lithium-rich sulfide all-solid-state lithium batteries

Résumé

Lithium-ion battery is the most effective electrochemical storage technology in terms of energy density nowadays. However, it is believed that the performances of this technology are close to their theoretical limits. Developing all-solid-state batteries in which the liquid electrolyte is replaced by a solid could be a way to overcome these limits. Firstly, the use of an organic liquid electrolyte is a safety issue due to the risk of thermal runaway and limits the operating temperature window of the system. Secondly, the use of a solid separator could block dendrites propagation and allows for the use of metallic lithium as an anode. The removal of the liquid electrolyte could also allow the manufacturing of thick cathodes if proper industrial processes are developed. Both perspectives may lead to a significant increase in energy density at the battery level.
