1. Introduction Lithium-sulfur (Li-S) batteries have garnered intensive research interest for advanced energy storage systems owing to the high theoretical gravimetric (E g) and volumetric (E v) energy densities (2600 Wh kg −1 and 2800 Wh L − 1), together with high abundance and environment amity of sulfur [1, 2].].
Lithium-sulfur all-solid-state battery (Li-S ASSB) technology has attracted attention as a safe, high-specific-energy (theoretically 2600 Wh kg −1), durable, and low-cost power source...
A high sulfur loading is an essential prerequisite for the practical application of lithium–sulfur batteries. However, it will inevitably exacerbate the shuttling effect and slow down the polysulfide conversion kinetics.

The lithium sulfur (Li–S) battery has attracted much attention due to its high energy density and the low cost of sulfur, but practical applications are still impeded by its short cycle life and low practical energy density due to polysulfide shuttle and low sulfur
To acquire a high capacity of the Li-S battery, the sulfur cathode should have a high sulfur loading (>5 mg cm −2), and the sulfur proportion in the sulfur/sulfur host composite should exceed 95 %. Accounting for the insulation of sulfur, the structure and morphology of the sulfur host are especially critical; these properties are affected by …
Owing to high specific energy, low cost, and environmental friendliness, lithium–sulfur (Li–S) batteries hold great promise to meet the increasing demand for advanced energy storage beyond portable electronics, and to …
