Lithium-sulfur (Li-S) batteries have garnered significant attention as promising next-generation energy storage solutions due to their high energy density and cost efficiency. However, the broad adoption of Li-S batteries is impeded by several critical issues. These include the intrinsically low conductivities of sulfur (S) and lithium sulfide (LiS), the polysulfide shuttle effect, and dendrite formation on the lithium (Li) electrode, among other challenges. Overcoming these obstacles is crucial to realizing the full potential of Li-S batteries. A key step towards improving Li-S battery performance is the optimization of electrolytes, with a particular focus on enhancing cell cyclability, rate capability, safety, and lifespan. This review examines the current advancements in various electrolyte additive options, including their concepts, designs, and materials, and how the electrolyte's final chemical and physical properties influence the overall performance of Li-S batteries. The aim is to provide a comprehensive framework for the rational selection of future electrolyte additives for Li-S batteries, based on the available concepts, and to evaluate the existing electrolyte additives.

The depletion of fossil fuels and the environmental impact of chemical batteries, coupled with the rapid proliferation of portable electronic devices and the Internet of Things (IoT), have created an urgent demand for high-performance, lightweight, and sustainable energy systems. Flexible triboelectric nanogenerators (TENGs) have emerged as a promising technology for powering self-sufficient devices, offering advantages such as simple structure, flexibility, low cost, and environmental adaptability. In particular, electrospun nanofiber-based TENGs stand out due to their enhanced surface area, superior charge collection capabilities, and improved mechanical durability.

Covalent organic frameworks (COFs) have shown promise as bifunctional catalysts to simultaneously mitigate shuttle effects and Li dendrite issues of lithium-sulfur (Li-S) batteries. However, the inherent low conductivity of the COFs has significantly limited their catalytic activity and stability. Herein, bifunctional catalytic activity and durability of the COF/MXene heterostructure are activated by tuning the surface curvatures of COFs interfaced with MXene.

Transition metal and metal oxide heterojunctions have been widely studied as bifunctional oxygen reduction/evolution reaction (ORR/OER) electrocatalysts for Zn-air batteries, but the dynamic changes of transition metal oxides and the interface during catalysis are still unclear. Here, bifunctional electrocatalyst of Co─CoNbO is reported, containing lattice interlocked Co nanodots and CoNbO nanorods, which construct a strong metal-support interaction (SMSI) interface. Unlike the recognition that transition metals mainly serve as ORR active sites and metal oxides as OER active sites, it is found that both ORR/OER sites originate from CoNbO, while Co acts as an electronic regulatory unit.

Lithium-sulfur (Li-S) batteries have attracted significant attention in recent years owing to their high theoretical energy density (2600 W h kg) and specific capacity (1675 mA h g), abundant reserves and environmental friendliness. However, the well-known poor electrical conductivity of sulfur/LiS, shuttle effect of lithium polysulfides (LiPSs) and formation of lithium dendrites during the cycling process extremely hinder the large-scale application of Li-S batteries. In this work, we designed and prepared poly(3,4-ethylenedioxythiophene) (PEDOT) and FeC nanoparticle co-decorated carbon nanofiber (CNF) membranes as self-supporting LiS hosts to improve the electrochemical performance of Li-S batteries.

The migration and shuttling of polysulfides between electrodes during the charge-discharge process pose a considerable challenge in the practical application of lithium-sulfur (Li-S) batteries. To address this, the development of functional separators represents an accessible and cost-effective approach to mitigate the shuttling effect and enhance the chemical kinetics of Li-S systems. In this study, a series of MOFs were constructed by tuning the central metal and used as separation modification to explore the effect of the metal ions in the MOFs on the catalytic conversion of polysulfides.
