Summary: To be commercially viable, sodium-ion batteries must offer long cycle life, good capacity, energy density, and safety. This study compared the performance of an ether-based non-flammable electrolyte with a carbonate-based electrolyte, showing higher efficiency and thermal stability with the former. Investigating SEI formation, it was found that the SEI formed using the non-flammable electrolyte was less resistive and more stable.

Summary: Metal solid-state batteries are considered the next-generation energy storage systems with high energy density and high safety. A strong and intimate solid-state interfacial contact between sodium metal and solid-state electrolyte is crucial for good cyclic stability at high current density. Inorganic electrolytes suffer from poor stability when cycled at low current density, leading to dendrite formation and loss of solid-solid contact at the interface. Further research and engineering approaches are needed to improve the integration of sodium metal with solid-state electrolytes and enhance electrochemical performance.

Summary: Electrolytes are essential for lithium-ion batteries, but traditional carbonate-based electrolytes are highly flammable. This study investigates the combustion characteristics of electrolyte and carbonate solvents with three types of flame retardants. The influence of lithium salt on the combustion process of carbonate mixed solvents is explored, and the flame-retardant effect of composite flame retardants on solvents is discussed. The results show that lithium salt greatly impacts the flame retardancy of carbonate mixed solvents, and the addition of flame retardants decreases the combustion rate and changes the flame shape of the solvents. Phenoxycyclophosphazene, melamine phosphate, and tris (2-chloropropyl) phosphate exhibit different flame retardant effects.

Summary: In this study, Fe(III) ions were incorporated into TiO2 hollow submicrospheres, which served as an excellent photocatalyst. The experimental parameters such as flow rate, rotation speed, and contaminant concentration were found to improve the catalyst activity. Fe-TiO2 hollow submicrospheres with different Fe wt% were prepared, and it was discovered that 2.5 wt% Fe-TiO2 exhibited the best photocatalyst activity. The Fe(III) doping not only increased the interaction between transition metal (Fe and Ti) 3d orbitals in TiO2, but also promoted the Fe(III)/Fe(II) redox kinetics and the associated photo-Fenton degradation of acetaminophen.

Summary: Carbon@titania yolk-shell nanostructures are successfully synthesized and used as a photocatalyst to degrade acetaminophen. The presence of residual carbon nanospheres is found to improve the photocatalytic efficiency. X-ray absorption spectroscopy analysis reveals the structural and electronic changes in the hollow shell. In situ XAS measurements show that the existence of amorphous carbon nanospheres inhibits the recombination of electron-hole pairs, leading to enhanced photodegradation of acetaminophen. Charge transfer from TiO2 to carbon nanospheres reduces electron-hole recombination and increases photocatalytic efficiency.

Summary: In this study, ordered L10 FeNi material was successfully synthesized through mechanical alloying and heat treatment methods under a magnetic field. The synchrotron-based X-ray diffraction technique confirmed that a 6-hour milling is sufficient to induce L10 FeNi formation, and a 12-hour milling achieved a chemically homogeneous powder. The magnetic properties study showed a slight decrease in magnetic saturation and a slight increase in coercivity with increasing milling duration, while heat treatment in a magnetic field significantly increased coercivity.

Summary: The WO3/BiVO4 heterojunction-based photoanodes have great potential in PEC water splitting. However, challenges such as resistive losses of TCO substrate and nonuniform deposition of co-catalyst hinder the development of large-area photoanodes. In this study, a patterned metal microgrid is used to reduce resistive losses and improve the uniformity of potential distribution. The combination of metal microgrid, large-area WO3/BiVO4 heterojunction, flow-induced uniform deposition of CoPi, and electrolyte flow in PEC cell design enhances the photocurrent and stability of large-area photoanodes. This research provides guidelines for improving the PEC performance of large-area photoanodes through electrochemical engineering strategies.
