Abstract

Abstract:

Spiro quaternary ammonium bromide was synthesized with 1, 4-dibromobutane, anhydrous potassium carbonate, and morpholine employed as starting materials, and serves as the intermediate for the preparation of spiro quaternary ammonium tetrafluoroborate (SQA-BF4) by an anion exchange method. The chemical composition and thermal stability of the as-prepared product were studied by means of Fourier transform infrared spectroscopy (FTIR), liquid chromatography-mass spectrum (LC-MS), nuclear magnetic resonance spectroscopy (NMR), and thermogravimetric analysis (TG). It is revealed that the as-synthesized product is SQA-BF4, which shows high thermal stability (up to 382℃ in N2). When used as the electrolyte for supercapacitors, SQA-BF4 shows better electrochemical properties than the common tetraethylammonium tetrafluoroborate electrolyte. The supercapacitor fabricated with active electrodes and SQA-BF4 electrolyte operates in a wide potential window of 0-3 V, exhibits high specific capacitance of 18.5 F·g-1, and delivers a high energy density of 83.4 Wh·kg-1.
