To realize a low-carbon economy and sustainable energy supply, the development of energy storage devices has aroused intensive attention. Lithium-sulfur (Li-S) batteries are regarded as one of the most promising next-generation battery devices because of their remarkable theoretical energy density, cost-effectiveness, and environmental benignity.
In this review, we describe the development trends of lithium-sulfur batteries (LiSBs) that use sulfur, which is an abundant non-metal and therefore suitable as an inexpensive cathode active material. The features of LiSBs are high weight energy density and low cost.
Lithium-sulfur batteries have received significant attention in the past few decades. Major efforts were made to overcome various challenges including the shuttle effect of polysulfides, volume expansion of cathodes, volume variation and lithium dendrite formation of Li anodes that hamper the commercialization of the energy storage systems.
Lithium-sulfur (Li-S) battery is recognized as one of the promising candidates to break through the specific energy limitations of commercial lithium-ion batteries given the high theoretical specific energy, environmental friendliness, and low cost.
One of the most promising battery systems that can fulfill the requirement is the lithium-sulfur (Li−S) battery. The theoretical specific energy of Li−S batteries is 2600 Wh kg −1, which is about five times higher than the current standard (430–570 Wh kg −1) for LIBs such as LiC 6 −LiCoO 2. 2 Besides, sulfur is abundant, affordable, and non-toxic.
In view of this, research and development are actively being conducted toward the commercialization of lithium-sulfur batteries, which do not use rare metals as the cathode active material and have high energy density; in addition, lithium and sulfur are naturally abundant.
