Regenerated hydrogel electrolyte towards an all-gel supercapacitor [PDF]

Science China Materials, 2021
Electrolyte regeneration is an important goal for environmental protection and sustainable development efforts. Herein, we report a facile strategy inspired by the transformation of edible dough from flour to regenerate hydrogel electrolytes from their dehydrated copolymer granules (CGs) via direct addition of water or salt solution.

An Insight into Synthesis of the Antifreeze Alkaline Hydrogel Electrolyte: Fine‐Tuning Chemistries for Efficient Ion Transport

ChemElectroChem, 2023
Herein, the chemical compatibility of the hydrogel electrolyte in highly alkaline pH was evaluated. Through simple experiments, we demonstrated that the frequently used polymer compound, acrylamide, is not stable at a high pH. The addition of glycerol as

Experimental investigation of the initial regime in fingering electrodeposition: dispersion relation and velocity measurements [PDF]

, 2002
Recently a fingering morphology, resembling the hydrodynamic Saffman-Taylor instability, was identified in the quasi-two-dimensional electrodeposition of copper. We present here measurements of the dispersion relation of the growing front.

Hydrogel-Polymer Electrolytes Based on Polyvinyl Alcohol and Hydroxyethylcellulose for Supercapacitor Applications

International Journal of Electrochemical Science, 2014
A transparent polymer-hydrogel electrolyte was successfully synthesized on the basis of polyvinyl alcohol (PVA). Sulfuric acid (H2SO4) as a dopant electrolyte was used to dissolve PVA.

Effect of stevia supplementation of kale juice spheres on their quality changes during refrigerated shelf life [PDF]

, 2018
Kale is a vegetable with high contents of health–promoting compounds although its consumption as a beverage is highly limited due to its bitter flavour. Nonetheless, the bitter flavour of Brassicas may be masked by sweetening.

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.
