High Performance of Sulfide-based Electrolytes in All Solid-State Batteries for Safe Applications of Electric Vehicles

Lithium-ion batteries (LIBs) have become a key player in the growing need for electric vehicles (EVs). State-of-the-art LIBs, using liquid electrolytes, still have significant challenges in their safety, lifespan, and energy density. Accordingly, solid-state lithium-ion batteries (SSLBs) have recently been attracting increasing research and industrial attention due to their ability to overcome intrinsic disadvantages of flammable liquid electrolytes used in current LIBs. The objective of this proposed research is to develop safe and high-performance SSLBs with sulfide-based electrolytes. The project includes two main directions: (1) synthesis of highly conductive and stable sulfide-based electrolytes; and (2) design of high-performance SSLBs with a stable interface between sulfide electrolytes and Li-ion cathode materials. 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.
