High-entropy perovskite oxide nanofibers as efficient bidirectional electrocatalyst of liquid-solid conversion processes in lithium-sulfur batteries

Liyuan Tian et al.

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.

Unraveling Polysulfide's Adsorption and Electrocatalytic Conversion on Metal Oxides for Li-S Batteries

Shungui Deng et al.

Summary: Lithium sulfur (Li-S) batteries hold great promise for next generation electronics and electrical vehicles due to their high theoretical capacity and energy density. However, the development of Li-S batteries is hindered by the shuttle effect and sluggish conversion kinetics of lithium polysulfides (LiPSs). This review provides a systematic analysis of the adsorption and catalytic mechanism in Li-S chemistry, discussing the role of metal oxides (MOs) as efficient catalysts and proposing oxygen vacancies and heterostructure engineering as effective strategies to improve the sluggish adsorption-diffusion-conversion process. The challenges and prospects of MOs electrocatalysts in Li-S batteries are also discussed.

The effect of pressure tuning on the structure and mechanical properties of high-entropy carbides

Shixue Guan et al.

Summary: High-purity (Ta0.2Nb0.2Hf0.2Zr0.2Ti0.2)C high-entropy ceramics were successfully synthesized by high-pressure solid-phase reactions. The formation route of high-entropy phase and the effect of pressure tuning on the structural and mechanical properties of the ceramics were systematically investigated. An interesting process was observed in which a double phase high-entropy carbide was formed, followed by the defusing of one phase into another, and the eventual formation of a high-entropy phase. Moreover, an abnormal, pressure-induced enhancement of the bulk modulus and strength was observed, resulting from the crystal plane distortion in high-entropy carbides.

Expediting the Conversion of Li2S2 to Li2S Enables High-Performance Li-S Batteries

Zhanshuang Jin et al.

Summary: The conversion of Li2S2 to Li2S is a crucial step in lithium-sulfur (Li-S) batteries, and the catalysts in these batteries are often ineffective due to poor contact with solid Li2S2. By designing pomegranate-like sulfur nanoclusters@nitrogen-doped carbon@nitrogen-doped carbon nanospheres (S@N-C@N-C NSs), the rapid conversion of ultrafine Li2S2 to Li2S can be achieved. The cathodes with this nanostructure exhibit excellent sulfur utilization, high rate performance, and low capacity decay rate, showing potential for energy storage applications.
