Synthesis of Sulfide-Based Solid Electrolytes for Application to All-Solid-State Lithium-Sulfur Batteries


William Wong and Linda Nazar (Chemistry)


Lithium–sulfur (Li-S) batteries are a promising candidate to support the demand for high energy density storage systems. The active material is sulfur, which presents the advantage of being abundant on earth, thus inexpensive, and environmentally friendly. However, the traditional use of conventional organic liquid electrolytes in these batteries prevents them from being commercialized because of hazards, such as flammability and leakages. One solution to overcome these issues is to use all-solid-state Li-S batteries. In this seminar, results on the synthesis of sulfide-based solid ionic conductors will be presented. Then, the performance of all-solid-state cells using different material compositions and morphologies will be compared.
