Summary: Transition metal oxides, especially high-entropy oxides (HEOs), have shown great potential as host materials for sulfur in lithium-sulfur (Li-S) batteries due to their strong polysulfide adsorption and catalytic effect. In this study, HEO nanofibers were designed as bidirectional catalytic hosts for sulfur, promoting both the reduction of soluble intermediates and the re-oxidation of insoluble products. The introduction of multiple metal elements effectively modulates the binding strength of soluble polysulfides, enabling the HEO nanofibers to act as bidirectional electrocatalysts for the conversion processes between soluble polysulfides and insoluble Li2S, resulting in high areal capacity and good cycle stability.

Summary: This study presents the use of pre-lithiated metallic 1T phase two-dimensional molybdenum disulfide (LixMoS2) as a sulfur host material for high-performance lithium-sulfur batteries. The lithiation of conductive MoS2 nanosheets leads to improved adsorption of lithium polysulfides, enhanced Li+ transport, accelerated electrochemical reaction kinetics, and superior electrocatalytic activity. The pouch cell batteries based on this design deliver a high energy density of 441 Wh kg(-1) and 735 Wh l(-1), with a capacity retention of 85.2% after 200 cycles.

Summary: The field of high entropy oxides (HEOs) challenges traditional materials science paradigms by studying the properties arising from profound configurational disorder caused by multiple elements sharing a single lattice site. This disorder can give HEOs functional properties that surpass their nondisordered counterparts. However, the true magnitude of configurational entropy and its role in stabilizing new phases and generating superior functional properties have been underexplored. Understanding configurational disorder in existing HEOs is crucial for rational design of new HEOs with targeted properties.

Summary: A scalable solvothermal method was used to synthesize NiCoMnZnMg-containing high-entropy glycerolate (HE-Gly) particles, which were then used as a precursor for porous high-entropy oxide (HEO) microparticles. The temperature of the annealing process and the composition of the metal ions in the HE-Gly precursors were found to be crucial in determining the porosity, crystallinity, and phase separation in HEOs. This study describes HE-Gly as a new precursor that can alter the composition, crystallinity, and porosity of HEOs, with potential for large-scale production and industrial applications of high-entropy materials.

The results showed a 7-fold increase in bacterial growth after 4 hours of interaction with quinary glycerolate particles compared to the control group. Microscopic studies revealed the release of metal cations from PGPs into the bacterial cytoplasm and the formation of bacterial biofilm on PGPs. Glycerol in PGPs was found to effectively control the release of metal cations, preventing bacterial toxicity.

Summary: In this work, the electrochemical analysis of lithium-sulfur batteries (LSB) was studied, with the positive electrode composed of sulfur and activated carbon (AC) and the negative electrode made of lithium metallic. Various techniques such as cyclic voltammetry, galvanostatic charge-discharge, and electrochemical impedance spectroscopy (EIS) were used for the in-situ characterization of the coin cell battery device. The findings include a high specific capacity of 1044 mAh gsulfur-1, which decreased to 200 mAh g-1 after 150 cycles, and an increase in coulombic efficiency during discharge. The electrochemical (in-situ) and ex-situ characterization of electrodes and coin cell devices provided valuable insights into the overall characteristics exhibited by LSBs.

Summary: The development of lithium-sulfur (Li-S) batteries with high energy density and cycling stability is hindered by the slow polysulfide conversion and adverse shuttling effects. Therefore, new electrocatalysts are needed to facilitate the practical applications of Li-S batteries. In this study, a single-phase high-entropy stabilized oxide (Ni0.2Co0.2Cu0.2Mg0.2Zn0.2)O is prepared and integrated into the sulfur host, functioning as both the catalytic converter and chemical inhibitor towards the shuttle species. The resulting cathode exhibits significantly improved discharge capacity and cycling stability compared to other cathodes, demonstrating the potential application of high-entropy oxides (HEOs) in enhancing the performance of Li-S batteries.

Summary: Li-S batteries are considered a promising alternative to Li-ion technology due to their high specific capacity and lower environmental impact and production costs. The shuttle effect, which involves the migration of lithium polysulfides from the cathode to the anode, is a major problem that affects Li-S batteries. This study presents a strategy to address the shuttle effect and improve the kinetics at the cathode by coating a functional layer of high entropy oxides onto the sulfur cathode.
