Özet

This study focuses on the development of next-generation polymer gel electrolytes that feature flexible structures, high ionic conductivity, and strong

electrochemical stability, aiming to advance energy storage systems. Crosslinked hydrogels were synthesized via redox-initiated polymerization of

acrylamide (AAm) and N,N'-methylenebisacrylamide (MBAAm) using a Ce(IV)/mercaptosuccinic acid initiator [1–2]. The resulting hydrogels were

modified with varying amounts of poly(vinylsulfonic acid sodium salt) (PVSANa) and different concentrations of the surfactant


Tricaprylylmethylammonium Chloride (Aliquat 336), along with nano-sized additives to enhance ion transport and structural uniformity, forming semi-

interpenetrating polymer networks (semi-IPNs) [3–4].


The hydrogels obtained were systematically characterized in terms of ionic conductivity, mechanical flexibility, and supercapacitor performance.

Characterizations were carried out using symmetric EDLC (electrochemical double-layer capacitor) devices with graphite electrodes, following the

methodologies described by Wang et al. [5].

In this study, for the first time, these innovative modified hydrogels demonstrate great potential as flexible solid-state electrolytes for supercapacitors and

batteries, due to their enhanced capacitance and mechanical compatibility. They hold promise for flexible energy storage materials and electronic

applications.
