چکیده
|
In this paper, the effect of cationic and anionic ion sizes on the charge storage capability of graphene nanosheets is investigated. the electrochemical properties of the produced electrode are studied using cyclic voltammetry (cv) and electrochemical impedance spectroscopy (eis) techniques in 3m nacl, naoh, and koh electrolytes. scanning electron microscopy (sem) is used to characterize the microstructure and nature of the prepared electrode. the sem images and x-ray diffraction (xrd) patterns confirm the layered structure (12 nm thickness) of the used graphene with an interlayer distance of 3.36 å. the electrochemical results and the ratio of q0*/ q1* confirm good charge storage and charge delivering capability of the prepared electrode in the 3m nacl electrolyte. charge/discharge cycling tests show a good reversibility and confirm that the solution resistance will increase after 500 cycles.
