3.1.3 Linear Sweep Voltammeter (LSV)
The linear sweep voltametric (LSV) response was measured to assess the electrochemical stability window with nanofiller doped polymer electrolyte films. Figure 4 implies the linear sweep voltammogram for a highest electric conductivity nanofiller enhanced polymer electrolyte layer from -2.5 V to 2.5 V. The polymer electrolyte film was placed among two SS electrodes for LSV analysis carried out by CH instrument workstation. It is evident that there is no faradic peak in the voltage range roughly between -1.8 V and 1.8 V. The outcome is a novel nanofiller doped solid electrolyte for EDLC application, with a nano filler doped polymer electrolyte layer exhibiting an ESW of about 4.01 V.
