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,

Inorganic Hydrogel Electrolyte with Liquidlike Ionic Conductivity

Electrochemical and Solid-State Letters, 2009
Hydrogel electrolytes, hydrotalcites holding different concentrations of KOH aqueous solutions, were prepared as a candidate for an electrolyte in all solid-state alkaline secondary batteries. The hydrogel electrolytes had high ionic conductivity (maximum 0.56 S cm -1 at 30°C) and diffusion coefficient of zincate (maximum 3.1 X 10 -6 cm 2 s -1 ...

Anti‐Fatigue Hydrogel Electrolyte for All‐Flexible Zn‐Ion Batteries

Advanced Materials, 2023
AbstractHydrogel electrolytes are widely explored in Zn metal batteries for application in wearable electronics. While extensive studies have been conducted on optimizing the chemical structure and boosting the tensile elasticity, the mechanical stability of the hydrogel under repeated deformation is largely overlooked, leading to unsatisfactory ...

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.

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 ...

Highly Swellable Hydrogel Electrolyte for Metal Air Battery

ECS Meeting Abstracts, 2016
Gels have three-dimensional cross-linked polymer network, which can extensively swell in water or hydrophilic solvents depending on their structure. High swelling property of the hydrogels can be very beneficial to use them as electrolyte material for battery application.

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.
