ABSTRACT
Lithium-sulfur (Li/S) battery chemistry has a long history. Early work and patents, including lithium anodes and sulfur-type cathodes, date back at least 50 years [1], owing to the potentially high energy densities of this system. Despite its long development history, rechargeable Li/S batteries have yet to reach performances suitable for competitive commercial markets. A measure of the growth in interest may be seen in the increasing number of peer-reviewed publications over the last few years [2] (Figure 5.1). To date, numerous vigorous efforts aimed at capitalizing on the promise of the unsurpassed gravimetric energy densities are continuing, and prog-ress is being made, albeit slowly.
