Are lithium-sulfur batteries the future of energy storage?

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.

Why are lithium-sulfur batteries important?

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.

What is lithium-sulfur battery?

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.

What are the research interests & research interests in lithium-sulfur batteries?

His research interests focus on advanced high-energy-density batteries such as lithium-sulfur batteries and lithium-metal batteries, especially on the chemical phenomena in the formation and evolution of electrode interface. He was recognized as a Highly Cited Researcher by Clarivate since 2018 in materials science and chemistry.

Why is lithium sulfide anode used in lithium ion battery?

However, its defect is that the stability of lithium metal with the sulfide electrolyte, so it usually uses lithium indium alloy anode, which will reduce the output voltage of the battery. In turn, the specific energy of the battery is reduced.

Is lithium-sulfur battery technology ready?

Conclusions Lithium-sulfur battery technology readiness and its applications were discussed and relevant studies were reviewed. Li-S was presented as a promising technology with advantages over alternative battery technologies in the market.
