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,

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.

Tough Hydrogel Electrolytes for Anti‐Freezing Zinc‐Ion Batteries

Advanced Materials, 2023
AbstractAs the soaring demand for energy storage continues to grow, batteries that can cope with extreme conditions are highly desired. Yet, existing battery materials are limited by weak mechanical properties and freeze‐vulnerability, prohibiting safe energy storage in devices that are exposed to low temperature and unusual mechanical impacts. Herein,

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 ...

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

Selection of hydrogel electrolytes for flexible zinc–air batteries

Materials Today Chemistry, 2021
Abstract Flexible zinc–air batteries attract more attention due to their high energy density, safety, environmental protection, and low cost. However, the traditional aqueous electrolyte has the disadvantages of leakage and water evaporation, which cannot meet application demand of flexible zinc–air batteries.
