La-doped ceria (Ce0.6La0.4O1.8 [LDC]) has been reported to be an effective buffer layer material for preventing the chemical reaction between Sr- and Mg-doped LaGaO3 (LSGM) electrolyte and Ni-based anode during sintering. However, it seems difficult to achieve a high power density on the cell...
Glass and glass ceramic are now well known for their high performances as sealants operating around 800 °C in solid oxide electrolyser cell. Several new formulations have been prepared and investigated: silica alkali borosilicate glass formulations that will create a glass sealant and calcium...
A well-known gasochromic material is Pt particle-dispersed tungsten trioxide (Pt/WO3). Its optical properties could make it effective as a hydrogen gas sensor. In this study, Pt nanoparticle-dispersed WO3 thin films were prepared using the sol–gel process, and their optical and electrical...
–(SiO2)100 − x
(0 < x < 40) xerogels have been produced by sol–gel methods either by partial pre-hydrolysis or reflux of tetraethoxysilane and titanium isopropoxide. These have been characterised by 29Si nuclear magnetic resonance, X-ray diffraction, EXAFS at the Ti–K edge,...
Overcharge performance of LiFePO4 cells is investigated through adding 2, 5-ditertbutyl 1, 4-dimethoxybenzene (DDB) as redox shuttle into electrolyte (RS electrolyte) at different charge rate. RS electrolytes with DDB works well as overcharge protection at low charge rate of less than 0.1 C....
PO4/C cathode materials are selectively synthesized by a solvothermal method in ethylene glycol solvent using glucose, LiCl, H3PO4, MnCl2·4H2O, and Co(NO3)2·6H2O as precursors. The obtained samples are characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), and...
A novel Nafion-sulfonated diphenyldimethoxysilane (N-sDDS) composite membrane is prepared and employed in vanadium redox flow battery (VRB). Ion exchange capacity, proton conductivity, water transport behavior, and the cell performances are characterized. Fourier transform-infrared and X-ray...
5LiFePO4⋅Li3V2(PO4)3/C composite cathode material is synthesized by a polyethylene glycol (PEG)-assisted rheological phase method. As a surfactant and dispersing agent, PEG can effectively inhabit the aggregation of colloidal particles during the formation of the gel. Meanwhile, PEG will coat on...
