Solid polymer electrolyte (SPEs) has drawn great attention nowadays, particularly in the field of science and applied science, specifically, those used as separators in industries and researchers for the assemblage of some “classified batteries” and super capacitors. In this report, we present the grandeur of this SPE (pure type), particularly at room temperature, such that, it can be applied as an electrolyte as well as a separator in supercapacitor fabrication. The SPEs were produced from the composition of polyvinyl alcohol (PVA) and Phosphoric acid (H3PO4), such that, the PVA samples were kept constant while the phosphoric acid was varied at 0, 10, 20, 30, 40, 50, 60, and 70 wt. %. After the experimentation, the pure polymers show excellent results in term conductivity, in that, it has recorded a conductivity as high as 2.56 x 10-3 Scm-1 at the compositions of 70 wt. %. Aside that, we also observed that, the bulk moduli (Rb) value decreases with the increase in concentration, with pure solid polymer electrolyte (PSPE) recording 2.5 ? at the highest composition of 70 wt. %.
