Description

The objective of this project is to design and develop all-solidstate lithium-sulfur (Li-S) batteries. Li-S batteries potentially have much higher theoretical energy density and lower cost than conventional Li-ion batteries, but their application is still restricted due to poor cycle life caused by sulfur loss from the cathode. Our Phase I will use a superionic solid electrolyte and sulfur-encapsulated carbon matrix to reduce sulfur loss to the electrolyte and to increase the sulfur utilization. The solid electrolyte powder will be made into thin films to reduce their area resistance. The full lithium-sulfur batteries based on these components will be constructed to evaluate their electrochemical performance. It is anticipated that the developed Li-S batteries may demonstrate desirably high energy and power density for some military vehicle applications.
