Název v původním jazyce

Surface modification of activated carbon with silver nanoparticles for electrochemical double layer capacitors

Popis výsledku v původním jazyce

In the present work, we report the synthesis of surface modified activated carbon (AC). The surface of the activated carbon have been modified by using silver nanoparticles. The synthesis process is simple, cost effective and environment friendly. The modified-AC powders have been characterized by using X-ray diffraction, scanning electron microscopy and surface area and pore size measurements. The electrochemical performance of the prepared materials have been tested by fabricating symmetric configuration of EDLC by using magnesium-ion based polymer electrolytes. The cells have been tested by using cyclic voltammetry, electrochemical impedance spectroscopy and galvanostatic charge-discharge technique. AC with 3 wt% of silver presents best results with specific capacitance of the order of 398 F gMINUS SIGN 1 energy density and power density of 55 Wh kgMINUS SIGN 1 and 2.4 kW kgMINUS SIGN 1 making it an interesting material for supercapacitor application.
