Preparation and Characterization of Organic-Inorganic Hybrid Hydrogel Electrolyte Using Alkaline Solution

Abstract

Organic-inorganic hybrid hydrogel electrolytes were prepared by mixing hydrotalcite, cross-linked potassium poly(acrylate) and 6 M KOH solution. The organicinorganic hybrid hydrogel electrolytes had high ionic conductivity (0.456-0.540 S cm −1 ) at 30 °C. Moreover, the mechanical strength of the hydrogel electrolytes was high enough to form a 2-3 mm thick freestanding membrane because of the reinforcement with hydrotalcite.

“…Therefore, compromising ionic conductivities and mechanical properties of solvent free polymer electrolytes is still not resolved completely. Gel polymer electrolytes (GPEs) have emerged as alternative candidates to address that crucial issue because they have appreciable ambient temperature ionic conductivities together with good mechanical properties [4,5]. In addition, they possess some distinct advantages over liquid electrolytes such as reduced leakage, low reactivity, and better shape flexibility.…”

Construction of All-Solid-State Nickel-Zinc Rechargeable Cell with Hybrid Hydrogel Electrolyte

“…In terms of handling, a self-standing membrane is required for an electrolyte in electrochemical devices, but both PHE and IHE are insufficient in mechanical strength. Recently, we have succeeded in preparing a new hydrogel electrolyte, organic-inorganic hybrid hydrogel electrolyte (HHE), by mixing hydrotalcite and PAAK powders with 6 M KOH solution (9). In this study, we assembled an all solid-state rechargeable Ni-Zn cell with a self-standing membrane of the HHE, and evaluated its electrochemical characteristics.…”
