New ionically conductive solids of polysaccharides containing excess water

Acidification of the electrolyte during the galvanic corrosion of AA7075: A numerical and experimental study

“…Also, EIS experiments in different agarose gel electrolytes have shown that double-layer capacitances on the electrode are equivalent to those in different aqueous electrolytes. 25 These features make the agar gel a very interesting medium to validate simulations about corrosion processes, as the transient propagation of some chemical species can visually be tracked by using a proper pH indicator.…”

Novel agarose polymer electrolyte for quasi-solid state dye-sensitized solar cell

“…Meanwhile, polysaccharide shows much lower crystallinity at room temperature compared to traditional PEO matrix. These may lead to high ionic conductivity, and excellent thermal and chemical stability of polysaccharide electrolyte [12][13][14], making it suitable for use as heterogeneous medium in photoenergy conversion [15][16][17]. Although excellent achievements have been reached in studying polysaccharide electrolyte, until now there are seldom studies which make systematic reporting on the ionic or electronic transport process in DSSCs with polysaccharide electrolyte.…”

Solid type dye-sensitized solar cell using polysaccharide containing redox electrolyte solution

“…Our group has reported that small ions and molecules can diffuse freely in the aqueous phase of the polysaccharide containing excess water with almost the same diffusion coefficient as in an aqueous solution [6][7][8]. The water of a polysaccharide solid was substituted by an organic liquid containing I À /I À 3 redox electrolyte used in a dye-sensitized solar cell by soaking the solid/water into the I À /I À 3 redox electrolyte solution of AN/MOZ (1:1), and the conductivity was measured by alternating current impedance spectroscopy.…”

“…The molecular diffusion [7] and ionic conductivity in this solid are almost the same as in liquid water [8], so that this solid can be used as an electrolyte medium instead of water for conventional electrochemistry and electrochemical measurement, and many devices. The hardness of the solid is, for instance, almost one third of a conventional rubber eraser for a 2 wt% j-carrageenan solid involving excess water.…”
