Supercapacitor-battery hybrid energy storage devices from an aqueous nitroxide radical active material

Abstract: A hybrid electrochemical energy storage device was fabricated in aqueous NaOH with the 2,2,6,6-tetramethyl-1-piperidinyloxy (TEMPO) nitroxide radical as the active material, hydroquinone as the counter electrode active material, and an OH − -selective separating membrane. The working principle of this device was investigated and it can be considered as a supercapacitor-battery hybrid energy storage system. Device performance was characterized by cyclic voltammetry and galvanostatic charge-discharge testing. Wh… Show more

“…Supercapacitors [1][2][3][4][5][6][7][8], called electrochemical capacitors, are one of the most efficient energy storage devices for application in portable electronics, electrical vehicles, power back-up and various microdevices because of the advantages of high power density, long cycle life and fast charge-discharge process [9][10][11][12]. Nevertheless, supercapacitors usually suffer from a lower energy density (normally less than 10 Wh kg −1 ) than batteries, which has severely limited their widespread application.…”
