Special Issue Information

Dear Colleagues,

Lithium-sulfur batteries (Li-S) have been recognized as very promising next-generation batteries due to their high theoretical capacities (1672 mAh g-1) and high theoretical energy densities (2552 Wh kg-1), low cost, and environmental friendliness. Furthermore, sulfur as an active material of the cell has certain advantages since it is an abundant element in nature, and it is considered an environmentally benign element compared to some transition metals used in lithium-ion batteries (LIBs). Despite these merits, numerous efforts have been made by experts in this technology over the last decade to achieve its commercialization, but it still represents a challenge for the scientific community.

In this context, advanced research in Li-S batteries is necessary to improve their current problems, mainly addressing new cathode manufacturing strategies, testing novel Li anodes, new additives in the electrolytes, and separators or interlayers.

This Special Issue on “Advances in Lithium-Sulfur Batteries” in Energies aims to present recent advances in the design and synthesis of new sulfur cathode structures, lithium metal protection, novel electrolyte formulations, separators and interlayers, binders, and current collectors. In addition, research works focused on electrochemical improvements, study of surface chemistry and in situ characterization, and scaling to pouch cells will be highlighted. Authors are invited to submit relevant full articles, short communications, and reviews.

The Li-S battery is exceptionally appealing as an alternative candidate beyond Li-ion battery technology due to its promising high specific energy capacity. However, several obstacles (e.g., polysulfides’ dissolution, shuttle effect, high volume expansion of cathode, etc.) remain and thus hinder the commercialization of the Li-S battery. To overcome these challenges, a fundamental study based on atomistic simulation could be very useful. In this work, a comprehensive investigation of the adsorption of electrolyte (solvent and salt) molecules, lithium sulfide, and polysulfide (Li2Sx with 2 x 8) molecules on the amorphous Al2O3 atomic layer deposition (ALD) surface was performed using first-principles density functional theory (DFT) calculations. The DFT results indicate that the amorphous Al2O3 ALD surface is selective in chemical adsorption towards lithium sulfide and polysulfide molecules compared to electrolytes. Based on this work, it suggests that the Al2O3 ALD is a promising coating material for Li-S battery electrodes to mitigate the shuttling problem of soluble polysulfides. Full article
