Summary: Vanadium Pentoxide (V2O5) and Tungsten Trioxide (WO3) films were used to create an all-solid-state electrochromic device (ECD) with fast response time and low voltage stable startup. By adjusting the oxygen flow and annealing temperature, optimal optical contrast (AT), coloring time (tc), and bleaching time (tb) were achieved. However, in the ITO/V2O5/gel-electrolyte/WO3/ITO device, the working voltage was measured as & PLUSMN;2.5 V, and the tc and tb were slightly longer.

Summary: In order to design solid state hybrid or all-inorganic electrochromic devices, alternative methods for depositing electrochromic metal oxide thin films need to be explored. The electrochromic performance of a hybrid device using plasma assisted atomic layer deposition (ALD) grown nickel oxide (NiO) thin film and viologen was studied. The films of NiO with a thickness of a few tens of nanometers were first deposited on silicon, and then on Fluorine-doped Tin Oxide (FTO)/glass substrates to fabricate the device. The as-prepared films were analyzed for their structural and morphological properties, and a solid state organic-inorganic hybrid electrochromic device was fabricated. The device demonstrated impressive electrochromic behavior with high coloration efficiency, contrast ratio, and cycle life/stability. The ALD grown films showed advantage over other methods in terms of the smoothness and crack-free nature, allowing for proper power utilization in color switching. These results provide a new way to fabricate high-performance hybrid solid state electrochromic devices.

Summary: This research focuses on depositing spinel aluminum doped LiMn2O4 using radio frequency magnetron sputtering as a cathode material for flexible high-voltage lithium ion batteries. By changing the deposition pressure and annealing temperature, the study found that the films became looser with increasing pressure, while annealing temperature could improve nanostructures, especially for z-axis distortion of Al doped spinel LiMn2O4. The results showed better performance of LiAl0.1Mn1.9O4 compared to LiMn2O4 in terms of charge-discharge retention and charge-transfer impedance.
