Multifunctional hydrogel‐based electrolytes for thermoelectrochromic devices

Journal of Applied Polymer Science, 2023
AbstractIn this work, we presented a new thermoelectrochromic device based on the preparation of a hydrogel‐based electrolyte derived from cellulose, namely hydroxypropyl cellulose, with thermochromic properties and a good ion conduction at atmospheric conditions.

Designing of zwitterionic proline hydrogel electrolytes for anti-freezing supercapacitors

Journal of Colloid and Interface Science, 2023
Hydrogel electrolytes containing a large amount of freezable water tend to freeze at subzero temperatures, which catastrophically reduces their ionic conductivity and thus limits their practical applications. In this work, we propose a new type anti-freezing hydrogel electrolyte based on an additive of zwitterionic proline, which can maintain high ...

Manganese Oxide Supercapacitor with Aqueous Hydrogel Electrolyte

ECS Transactions, 2008
Two poly(acrylic acid)-based gel electrolytes have been characterized for their application to MnO2•nH2O supercapacitors. The gel polymer electrolytes (GPEs) consist of either poly(acrylic acid) or poly (acrylic acid)-co-poly(acrylamide) with 1 M KCl aqueous solution (weight composition, polymer : KCl : H2O = 9%: 6.7%: 84.3%). The GPEs show no fluidity,

Hydrogel, the Next‐Generation Electrolyte for Electrochromic Devices

physica status solidi (RRL) – Rapid Research Letters, 2023
Electrolytes have become a research frontier in the electrochromic community owing to their widespread applications in advanced electronic devices especially in electrochromic devices (ECDs). However, traditional ECDs with liquid electrolytes commonly suffer from inflexibility, complicated configurations, and poor electrochromic properties.

Drying of SnO2 hydrogels: effect of the electrolyte

Journal of Non-Crystalline Solids, 1992
Abstract The effect of the electrolyte (NH+4, Cl−) on the drying of SnO2 hydrogels was investigated by linear shrinkage, mass loss, gravimetric thermal analysis and infrared spectroscopy. Results show that the drying mechanism for monolithic SnO2 gels is highly dependent on the concentration of the electrolyte solution inside the pores.

An Intrinsically Stretchable and Compressible Supercapacitor Containing a Polyacrylamide Hydrogel Electrolyte

Angewandte Chemie - International Edition, 2017
AbstractStretchability and compressibility of supercapacitors is an essential element of modern electronics, such as flexible, wearable devices. Widely used polyvinyl alcohol‐based electrolytes are neither very stretchable nor compressible, which fundamentally limits the realization of supercapacitors with high stretchability and compressibility. A new
