Abstract: A series of Na 2 O-doped glassy systems, represented as xNa 2 O - (1 - x)(0.3 PbCl 2 - 0.1 ZnO - 0.6 V 2 O 5), with x values of 0, 0.05, 0.1, and 0.2, were prepared using a melt quenching method. The electrical conductivity of as-developed samples was examined over a wide range of temperatures and frequencies. High-frequency dispersion in the AC conductivity spectra was indicated by the frequency exponent (n) values, which suggest a percolation type of motion for charge carriers. The power law pre-factor (A) was utilized to investigate the strong composition dependence of the system. Variations in power factors (n and S values) may be attributed to mixed charge carrier conduction. Additionally, Na+ intercalation pseudocapacitance might facilitate rapid ion diffusion through one-dimensional, two-dimensional, or three-dimensional transport pathways that involve Faradaic charge transfer. Notably, the specific capacitance (C sp) increases from 60.51 F g−1 for x = 0 to 88.57 F g−1 for x = 0.05, highlighting significant enhancement due to greater open surface area. This suggests that the current system can be considered a supercapacitor within the category of pseudocapacitance-diffusion-controlled Faradaic systems. Furthermore, the specific energy shows an increase of 6.3 %, while the specific power decreases by 20 % with the addition of a small amount of Na to the host system. These characteristics underscore the potential of this system as an effective supercapacitor. • Na 2 O doped Glassy system as supercapacitor. • AC Conductivity and Complex Impedance Plots. • Na+ intercalation pseudocapacitance. • Significant increment of specific capacitance. • Specific energy increases by 6.3 % and specific power decreases by 20 %.
