Summary: Lithium-sulfur batteries have potential as new-generation energy storage devices due to their high theoretical energy density and the advantages of sulfur cathodes. However, they face challenges such as low utilization of active materials, volume expansion of the cathode, and loss of active materials. Graphene has been explored as a sulfur host material, but there is still an issue with sulfur escaping from the cathode. Various graphene-based materials with unique structures and chemical compositions have been studied to address this issue. This review summarizes the research progress of three-dimensional graphene, graphene with modified surface chemistry, graphene-based composites, and graphene-based flexible materials as sulfur hosts for lithium-sulfur batteries.

Summary: A thin (MXene/PP/Cu-TCPP) Janus separator was designed to address the rapid capacity fading and poor safety of lithium-sulfur batteries. The separator had an anisotropic spatial heterogeneity, with a sulfophile cathode-facing surface and a multifunctional ionic sieve on the opposite side. The MXene layer acted as an expanded S host, confining sulfur and its intermediates, while the MOF layer served as an ionic sieve and prevented dendritic growth of Li.

Summary: Lithium-sulfur (Li-S) batteries are highly promising high-energy-density secondary batteries due to their ultrahigh energy density and low cost. A dual-functional electrolyte additive, lithium selenide (Li2Se), is proposed to address the challenges faced by Li-SPAN batteries, including sluggish sulfur kinetics and uncontrollable Li deposition. Li2Se improves kinetics by attacking polysulfides and forms a stable selenide-containing organic-inorganic hybrid solid electrolyte interphase (SEI) to enhance Li deposition. The Li2Se-assisted Li-SPAN battery exhibits high discharge capacities, enhanced rate performance, and outstanding cycling stability.
