Potential of functional gel polymers as electrolytes for supercapacitors

Functional gel polymer electrolytes (FGPEs) have emerged as promising materials for supercapacitors due to their unique properties, such as high ionic conductivity, mechanical flexibility, and chemical stability. This review paper presents an overview of the current state of research on FGPEs, including their synthesis, characterization, and electrochemical properties. The various types of FGPEs and their applications in different supercapacitor configurations, such as symmetric and asymmetric, are discussed. In addition, the advantages and limitations of FGPEs are analysed, along with the challenges and opportunities for further development. Overall, FGPEs represent a promising avenue for advancing the performance of supercapacitors, and further research in this area is warranted.
