Electrochemical performance of a Li+-enriched metallohydrogel as an electrolyte and electrode material for supercapacitors

Abstract

Li⁺-enriched metallohydrogel (MG-Co) has been synthesized via in situ LiOH deprotonation of the pre-gelator (H₉SAL) followed by coordination with Co²⁺ to develop a pure gel electrolyte and electrode material without adding any external dopant to the gel matrix. The electrochemical performance of MG-Co as an electrolyte and electrode material has shown promising features to be utilized in supercapacitor applications.
