Composite materials for all-solid-state lithium-sulfur batteries
Lithium-sulfur batteries have a five times higher theoretical energy density than state-of-the-art Li-ion batteries. In addition, sulfur is abundant, inexpensive, and low in toxicity. However, the solubility of lithium polysulfides in liquid electrolytes limits the sulfur utilization rate, as well as the number of charge/discharge cycles.
