As a result of the electrochemical measurements, it is determined by experimental observations that the specific capacitance value of the tetravalent (B-2) electrode is higher than that of trivalent (B-1) in the presence of both different electrolyte solutions. Furthermore, when the morphological properties of both materials are examined, it is observed that tetravalent boronate ester (B-2) has a more porous structure and its surface area is higher than trivalent boronate ester (B-1) as a conclusion of the surface area measurement. As a consequence of this research, it has been demonstrated that tetravalent boronate ester (B-2) can be employed as a promising material for future supercapacitor energy storage applications.eninfo:eu-repo/semantics/closedAccessBoron estersCapacitanceCharacterizationEnergy storageSupercapacitorArticle281151995210Q3WOS:000849285100001Q12-s2.0-8513725649610.1007/s11581-022-04729-7
