Polymer Infiltration

Composite electrolytes containing lithium ion conducting polymer matrix and ceramic filler are promising solid-state electrolytes for all solid-state lithium ion batteries due to their wide electrochemical stability window, high lithium ion conductivity and low electrode/electrolyte interfacial resistance. In this study, we report on the polymer infiltration of porous thin films of aluminum-doped cubic garnet fabricated via a combination of nebulized spray pyrolysis and spin coating with subsequent post annealing at 1173 K. This method offers a simple and easy route for the fabrication of a three-dimensional porous garnet network with a thickness in the range of 50 to 100 µm, which could be used as the ceramic backbone providing a continuous pathway for lithium ion transport in composite electrolytes. The porous microstructure of the fabricated thin films is confirmed via scanning electron microscopy. Ionic conductivity of the pristine films is determined via electrochemical impedance spectroscopy. We show that annealing times have a significant impact on the ionic conductivity of the films. The subsequent polymer infiltration of the porous garnet films shows a maximum ionic conductivity of 5.3 × 10−7 S cm−1 at 298 K, which is six orders of magnitude higher than the pristine porous garnet film.

Wo3 Thin Films

Electrochromic phenomenon is an emerging technology for renewable energy applications. Several material oxides used for the electrochromic application, the tungsten oxide (WO3) has shown good coloration efficiency (CE). Present manuscript, we are reporting the results of the coloration efficiency of DC magnetron sputtered WO3 films for electrochromic applications (thicknesses 190 nm to 700 nm) with sputter gas neon at 300 K. Hydrogen and Lithium ions have been intercalated into WO3 lattice for coloration. The CE value is increasing with increase of thickness of WO3 thin films; CE for 700 nm thick films are: 87 cm2/C and 137 cm2/C for H+ and Li+ respectively. The coloration efficiency (CE) observed to be increasing with wavelength. The maximum efficiency of the hydrogen intercalated neon sputtered films achieved at 860 nm wavelength is about 129.9 cm2/C and for the lithium intercalatedWO3 films the maximum efficiency achieved at 780 nm with 238.5 cm2/C. These neon sputtered WO3 thin films show good stability of coloration efficiency even after 500 cycles of coloring and bleaching cycles. The work function of the colored and transparent states of WO3 thin films are 4.513 eV and 4.755 eV respectively. Finally we have fabricated the electrochromic device (ECD) prepared with nafion thin film as an ion conducting layer and the ECD has shown a maximum coloration efficiency (CE) of 112.1 cm2/C.
