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
