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.

Are lithium-sulfur (Li-S) batteries a good choice for next-generation rechargeable batteries?

To meet the great demand of high energy density, enhanced safety and cost-effectiveness, lithium-sulfur (Li-S) batteries are regarded as one of the most promising candidates for the next-generation rechargeable batteries.

Are Li-S batteries lithiophilic?

Even at high current density of 2 C, the Li-S cells afforded a specific discharge capacity of around 672 mAh g −1 after 500 cycles with 87.1% retention and high CE of 99% . Chen and coworkers also constructed a lithiophilic interface of Sb on Li metal for application in Li-S batteries .

How to protect lithium metal in Li-S batteries?

Tremendous efforts have been made in the past few years to develop suitable artificial layers of SEIs for the protection of lithium metal in Li-S batteries. Various methods have been employed including direct coating, spray/sputter coating, and chemical coating, as discussed in more details subsequently.

What is the pretreatment stage of a lithium ion battery?

It begins with a preparation stage that sorts the various Li-ion battery types, discharges the batteries, and then dismantles the batteries ready for the pretreatment stage. The subsequent pretreatment stage is designed to separate high-value metals from nonrecoverable materials.

What are the challenges of Li-s battery characterization?

Another challenge for the in-situ characterizations is the detection of the surface or interfacial reactions, which is very important for the Li-S battery investigations. Soft X-ray spectroscopy technique, with less than a-few-hundred nanometers depth of penetration, is one of the only choices to probe the surface structure.
