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 ...

Altering the Zn2+ Migration Mechanism Enables the Composite Hydrogel Electrolytes with High Zn2+ Conduction and Superior Anti‐Dehydration

Advanced Functional Materials
Hydrogel electrolytes are favored for flexible zinc‐ion batteries (FZIBs) due to their biocompatibility. Their application progress, however, is severely restricted by the poor water retention and low Zn2+ transference number (tZn2+).

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.
