Summary: In this work, WO3 nanopowder was synthesized, and MoS2/WO3 nanocomposite was prepared. The addition of MoS2 in WO3 led to the formation of layered nanostructures and change in morphology. The electrochemical properties of the nanocomposites improved due to the large active surface area. The nanocomposites also exhibited good optical properties at low MoS2 contents.

Summary: In this study, the influence of deposition pressure on the electrochemical properties and memory effect of electrochromic tungsten oxide thin films was investigated. Three types of WO3 films were observed: irreversible blue coloration, reversible coloration with a high memory effect, and reversible coloration with a low memory effect. The discrepancies in the memory effect were attributed to the composition, local atomic environment, and morphology of the WO3 films. The study also recorded a decrease in transmittance at 550 nm of 15.8% in 48 h in air and 5.2% in 24 h in the electrolyte, highlighting the importance of morphology as a key parameter in low-energy consumption electrochromic devices.

A stable WO3/MoO3 suspension with a nanoheterojunction structure was obtained after grinding treatment. The ground WO3/MoOx composite film exhibited enhanced electrochromic performance due to its morphology and enhanced electron transfer. A complementary electrochromic device (ECD) using ground WO3/MoOx showed high transmittance modulation, fast switching times, high coloration efficiency, and cycling stability.

Summary: This study investigates the dynamic phase transformation and morphology evolution of h-WO3 nanowire during deep lithiation using an in situ single nanowire-based cell. It reveals the irreversible transformation from h-WO3 to Li2WO4 and the presence of deep ion-trapping sites in the Li2WO4 crystal structure. By triggering lithium-ion migration at the WO3/electrolyte interface and visualizing nanoscale lithium-ion migration, the mechanism of irreversible WO3-to-Li2WO4 transformation in deep lithiation reaction is demonstrated.
