Summary: In this study, a conductive NiCo2O4@PPy micro-flower-like material was synthesized and applied in Li-S batteries to improve the electrochemical performance. NiCo2O4@PPy material expedites the conversion of polysulfides through physical adsorption and chemical anchoring, while polypyrrole can effectively confine polysulfides shuttling, increase conductivity, and promote lithium ions diffusion. The composite exhibits satisfactory electrochemical performance and is a competent candidate for sulfur host material and interlayer in high-performance Li-S batteries.

Summary: Lithium-sulfur (Li-S) batteries are promising for high energy density applications, but the dissolution of Li polysulfides in the electrolyte hinders their practical use. The addition of a highly concentrated sulfolane-based electrolyte can solve this problem, but it decreases the reversibility of the Li-metal anode. By adding potassium FSI (KFSI) as an electrolyte additive, a stable solid electrolyte interface (SEI) can be formed at the Li anode, significantly improving the Coulombic efficiency and cycle stability of Li-S batteries. These results demonstrate the effectiveness of KFSI in protecting Li-metal anodes and enhancing the performance of Li-S batteries.

Summary: A hierarchically porous membrane loaded with fully dispersed single-layered MXene was fabricated for a high-areal-capacity Li-S battery. The membrane exhibited a 3D hierarchical porous structure that strengthened Li+ and electron transportation, accommodated sulfur volumetric expansion, enabled high sulfur loading, and provided ample active sites for LiPSs anchoring. The uniformly dispersed Ti3C2Tx nanosheets in the membrane prevented restacking of the MXene layer, contributing to enhanced Li+ diffusion and LiPSs adsorption and catalysis. The Li-S batteries showed high specific capacity and cycle stability at high sulfur loading. This facile strategy provides insights for the design of novel cathode materials for high-areal-capacity Li-S batteries.

Summary: Modern technologies in extreme environments, such as the sea, poles, or aerospace, require reliable batteries that perform well at temperatures below zero degrees. However, commercially available lithium-ion batteries (LIBs) tend to experience significant degradation in performance under low-temperature conditions. This review explores the challenges faced by each component of LIBs (anode, cathode, and electrolyte) in low-temperature environments and discusses potential modification methods and practical solutions to enhance their performance in such conditions. Furthermore, it highlights research gaps that deserve more attention in order to enable LIBs to operate at ultra-low temperatures.

Summary: This study investigates the influence of prestrain-induced dislocations on the formation of both coherent and incoherent precipitates in medium-entropy alloys (MEAs). The results show that prestrain increases the formation of incoherent precipitates and refines their size, while having little effect on the formation of coherent precipitates. By regulating the formation of precipitates, the room-temperature tensile properties of the alloy are improved.

Summary: The research on 3D batteries with large surface area and high active material mass loading is driven by the goal to increase the energy and power density of conventional 2D lithium-ion batteries. However, the challenge lies in removing the separator and coating the scaffolded areas of the electrode uniformly. In this paper, electrophoretic deposition technique was used to coat 3D NiO on the nickel foam anode with polyethylene oxide gel-polymer electrolyte, resulting in a thin and uniform polymer electrolyte. The NiO@Ni foam anode coated by PEO gel-polymer electrolyte showed excellent cycling stability and capacity, allowing for cell operation at room temperature without a commercial separator.

Summary: Heterostructures based on layered materials with unique mechanical, physical, and chemical properties are promising as next-generation photocatalysts. In this study, we systematically investigated a 2D monolayer WSe2/Cs4AgBiBr8 heterostructure, revealing it to be a type-II heterostructure with high optical absorption and improved optoelectronic properties. By introducing a suitable Se vacancy, the heterostructure transformed from an indirect to direct bandgap semiconductor. Furthermore, we found that the heterostructure was more stable when the Se vacancy was located near the vertical direction of the upper Br atoms. This insightful understanding of the WSe2/Cs4AgBiBr8 heterostructure and defect engineering provides valuable strategies for designing superior layered photodetectors.

Summary: There is a growing focus on different technologies used in energy production and storage, ranging from small-scale to large-scale applications, which are equally important. Li-ion batteries are currently the market leader in energy storage systems due to their high energy and power density. However, the scarcity of lithium resources and other metals for cathode materials in the long run is a significant concern. Recent research has looked into alternative energy storage systems, and sodium-ion batteries (SIBs) are considered the most promising next-generation alternative due to sodium's widespread availability and similar chemistry to lithium-ion batteries. The Na2Mn3O7 electrode has shown high capacity as a cathode material and is particularly attractive due to the low price of sodium and manganese. This work summarizes the recent progress in studying and enhancing the Na2Mn3O7 cathode material.
