Hydrogel membrane electrolyte for electrochemical capacitors

Journal of Chemical Sciences, 2009
Polymer electrolytes are known to possess excellent physicochemical properties that are very useful for electrochemical energy systems. The mobility in polymer electrolytes is understood to be mainly due to the segmental motion of polymer chains and the ion transport is generally restricted to the amorphous phase of the polymer.

Transport of non-associated electrolytes in acrylamide hydrogels [PDF]

Journal of Molecular Liquids, 2001
Abstract Diffusion of non-associated electrolytes (LiCl and KCl) in different hydrogels has been studied to identify the mechanism of electrolyte interaction with the structure of hydrogels and its dependence on electrolyte concentration and thermodynamic features of the electrolyte. Hydrogel membranes have been prepared from acrylamide (AAm) using N,
