چکیده انگلیسی
The study examined how a PVA-KOH-based GPE solution can be processed by screen printing and slot-die coating. It proved that the industrial application methods were suitable for coating a GPE layer directly on a supercapacitor electrode as well as for producing free-standing GPE layers. The influence of additives on flow properties was determined via rheological measurements. To evaluate the electrochemical performance, test cells for galvanostatic charge-discharge experiments and impedance spectroscopy measurements were built. It was found that cells containing a GPE layer produced with screen printing and slot-die coating show good cyclability. At a current density of 2Â mAÂ cmâ2, the cells with the slot-die-coated GPE layer reached a specific capacitance of 87.3Â Fgâ1 and at 50Â mAÂ cmâ2 a specific capacitance of up to 28.5Â Fgâ1. Different layer thicknesses have been realized by varying the parameters of the application methods. The influence of layer thickness on conductivity and specific capacitance was analysed using casted layers. It was found that an optimum exists between the layer thickness of the electrolyte layer and its molar concentration.
