Rechargeable Li–S batteries have received ever-increasing attention recently due to their high theoretical specific energy density, which is 3 to 5 times higher than that of Li ion batteries based on intercalation reactions. Li–S batteries may represent a next-generation energy storage system, particularly for large scale applications. The obstacles to

In Situ Techniques for Developing Robust Li–S Batteries [PDF]
AbstractRechargeable lithium–sulfur batteries (LSBs) are of great interest in the field of energy storage due to their favorable operational characteristics, for example, high theoretical energy density and low cost. However, LSBs are limited by long‐term degradation, caused by the dissolution of intermediate lithium polysulfide phases.

Insight into Sulfur Reactions in Li–S Batteries
ACS Applied Materials & Interfaces, 2014Understanding and controlling the sulfur reduction species (Li2Sx, 1 ≤ x ≤ 8) under realistic battery conditions are essential for the development of advanced practical Li-S cells that can reach their full theoretical capacity. However, it has been a great challenge to probe the sulfur reduction intermediates and products because of the lack of methods.

The Role of Metal Disulfide Interlayer in Li–S Batteries
The Journal of Physical Chemistry C, 2017Recently many observations related to the catalytic effects of layered metal disulfide versus polysulfide electrochemistry were documented. In this work, we investigated the reactivity of layered WS2 in a Li-S battery and observed a chemical reaction involving the removal of W ions by polysulfides. The presence of metallic tungsten nanoparticles in the
