High-Performance Sulfide-Electrolyte-Based All-Solid-State Lithium-Sulfur Batteries for Safe Electric Vehicle Applications

Lithium-sulfur (Li-S) batteries have been considered as one of the most promising candidates to meet the energy storage demand for electric vehicles due to their high theoretical energy density of 2600 Wh kg-1, low cost, natural abundance, environmental friendliness. State-of-the-art Li-S batteries, using liquid electrolytes, still have significant challenges in their safety and lifespan. Accordingly, solid-state Li-S batteries (SSLSBs) have recently been attracting increasing research and industrial attention due to their ability to overcome intrinsic disadvantages of flammable liquid electrolytes used in current Li-S batteries. The objective of this proposed research is to develop safe and high-performance SSLSBs with sulfide-based electrolytes. The project includes three main directions: (1) preparation of highly conductive thin sulfide electrolytes film; (2) development effective Li protection strategies to realize the combination of sulfide electrolytes with Li metal anode, and (3) design of high-performance SSLSBs with a stable interface between sulfide electrolytes and sulfur cathodes. GLABAT SOLID-STATE BATTERY INC. as an industrial partner will support and be involved in this project. The innovative research will help both GLABAT and Canada increase their global competitiveness and create new economic ventures.
