Cellulose hydrogel as a flexible gel electrolyte layer

MRS Communications, 2019
We report the synthesis of a novel polymer gel electrolyte primarily based on cellulose extracted from wood along with gelatin, polyacrylic acid (PAA) and potassium hydroxide (KOH) added as additives in minute amounts in various stages. We also study and report the variation of ionic conductivity with variation of various additives. We found that, with

New Electric Double Layer Capacitor with Polymer Hydrogel Electrolyte

Electrochemical and Solid-State Letters, 2003
A new electric double layer capacitor (EDLC) was constructed by using polymer hydrogel electrolyte prepared from cross-linked potassium poly(acrylate) and a KOH aqueous solution. The electrochemical characteristics of theEDLC cell were investigated by cyclic voltammetry and charge/discharge cycle testing compared with those of the cell using only a KOH

Biosourced Hydrogel Electrolytes for Aqueous Solar Cells

2019
Dye-sensitized solar cells (DSSCs) with water-based electrolytes are considered as one of the possible breakthrough towards DSSCs large-scale diffusion. If opportunely developed and optimized, aqueous solar cells can be considered a truly low impact photovoltaic device and no toxic components. Moreover, the possibility of gelling the electrolyte into a
