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,

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.

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 ...

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
