The suspensionswere then spray deposited onto 2 1 cm carbon papers. Theelectrodes were dried under vacuum at room temperature for 6 h.The electrochemical properties and capacitance measurements ofthe supercapacitor electrodes were studied in a three-electrodehalf-cell system in 1 M KOH electrolyte with Solartron analyticalequipment (Model 1470E). Platinum wire was used as a counterelectrode and Ag/AgCl as the reference electrode,查看更多
