Ti species have been deposited on low-voltage etched aluminum foils by a simple electrochemical method using a Ti anode as Ti source in a Ti-free I 2 -dissolved acetone solution. After annealing at 500-600 °C in air, an Al 2 O 3 -TiO 2 composite oxide film was formed on the surface of the etched aluminum foil by anodizing galvanostatically in an ammonium adipate solution. The effects of I 2 concentration in the acetone solution, applied anode voltage, electrolysis time, and annealing temperature on the specific capacitance of the aluminum anode foils were investigated. The TiO 2 -deposited specimens prepared by applying a potential of 50 V for 3 min in 2.5 mM I 2 -added acetone solution followed by annealing at 550 °C after anodization exhibited the highest specific capacitance, with an enhancement of 22% compared with pure etched aluminum foil specimens. The electrodeposition process and the change of the anode voltage during the anodization were analyzed. electrodeposition, titanium oxide, composite film, aluminum electrolytic capacitor, anodization

“…A maximum power density of 296 mW cm -2 was deposition time, use of simple equipment, low cost and suitability for mass production. EPD has also been used in SOFC technology for deposition of oxygen ion conductor electrolyte thick films on anode or cathode porous substrates [22][23][24][25][26][27][28]. To the best of our knowledge, apart from our preliminary study [29], EPD was never used for the deposition of proton conductor electrolyte thick films.…”

Intermediate temperature solid oxide fuel cells (IT‐SOFCs) were fabricated depositing proton conducting BaCe0.9Y0.1O3–x (BCY10) thick films on cermet substrates made of nickel oxide–yttrium doped barium cerate (NiO–BCY10) using electrophoretic deposition (EPD) technique. The influence of the EPD parameters on the microstructure and electrical properties of BCY10 thick films was investigated. Deposited BCY10 thick films together with green anode substrates were co‐sintered in a single heating treatment at 1,550 °C for 2 h to obtain dense electrolyte and suitably porous anodes. The half‐cells were characterised by field emission scanning electron microscopy (FE‐SEM) and by X‐ray diffraction (XRD) analysis. A composite cathode specifically developed for BCY electrolytes, made of La0.8Sr0.2Co0.8Fe0.2O3(LSCF, mixed oxygen‐ion/electronic conductor) and BaCe0.9Yb0.1O3–δ (10YbBC, mixed protonic/electronic conductor), was used. Fuel cells were prepared by slurry coating the composite cathode on the co‐sintered half‐cells. Fuel cell tests and electrochemical impedance spectroscopy (EIS) were performed in the 550–700 °C temperature range. A maximum power density of 296 mW cm–2 was achieved at 700 °C for electrolyte deposited at 60 V for 1 min.

“…The second step involves deposition of the colloidal particles on the electrode surface to form a uniform film. EPD has proven useful in many applications such as the assembly of nanoparticles to form nanoparticle films [23][24][25] solid oxide fuel cell (SOFC) fabrication [26], hybrid material synthesis [27], and graphene oxide [28].…”

. (2013). Facile synthesis of reduced graphene oxide/MWNTs nanocomposite supercapacitor materials tested as electrophoretically deposited films on glassy carbon electrodes. Journal of Applied Electrochemistry, 43 (9), 865-877.Facile synthesis of reduced graphene oxide/MWNTs nanocomposite supercapacitor materials tested as electrophoretically deposited films on glassy carbon electrodes AbstractThis paper reports on a facile synthesis method for reduced graphene oxide (rGO)/multi-walled carbon nanotubes (MWNTs) nanocomposites. The initial step involves the use of graphene oxide to disperse the MWNTs, with subsequent reduction of the resultant graphene oxide/MWNTs composites using l-ascorbic acid (LAA) as a mild reductant. Reduction by LAA preserves the interaction between the rGO sheets and MWNTs. The dispersion-containing rGO/MWNTs composites was characterized and electrophoretically deposited anodically onto glassy carbon electrodes to form high surface area films for capacitance testing. Pseudo capacitance peaks were observed in the rGO/MWNTs composite electrodes, resulting in superior performance with capacitance values up to 134.3 F g-1 recorded. This capacitance value is higher than those observed for LAA-reduced GO (LAA-rGO) (63.5 F g-1), electrochemically reduced GO (EC-rGO) (27.6 F g-1), or electrochemically reduced GO/MWNTs (EC-rGO/MWNTs) (98.4 F g-1)-based electrodes.
