Lithium Sulfur Batteries

Lithium sulfur batteries are considered to be the most promising high energy storage devices for electric vehicles in future. The ultra-high theoretical energy density and economic material cost make Li-S batteries receiving extensive concern recently. In our group, we have developed different kinds of carbon materials and coating materials for sulfur cathodes. In terms of the practical applications of Li-S batteries, our research interests include:

(1) High performance sulfur cathodes with high sulfur loading;

(2) Promising safe Li metal anodes in Li-S batteries;

(3) Safe electrolyte development and reveal detailed mechanism of Li-S batteries.
