Lithium ion batteries (LIB) have proven a key enabling technology for consumer electronics and are setting the stage for a revolution in transportation. Electric vehicles (EV), whether on land, sea, or air, are increasingly gaining market share over vehicles powered by the traditional combustion engine.
Existing batteries suffer from performance deficiencies, for example, they have limited power density and may drain rapidly when used for certain applications. By employing sulfur in their cathodes, LiS batteries can realize substantially greater energy densities than existing energy storage devices. Sulfur by itself is not a suitable electrode material due to its poor conductivity. Cathode materials for rechargeable secondary batteries such as LiS batteries may contain carbon as an amorphous conductive material.
