Abstract
Poly(vinyl butyral) (PVB) is of particular interest because of its low cost, extremely wide temperature work range (− 20 to 120 °C), and efficient chemical stability. In this study, a gel polymer electrolyte (GPE) containing Li+ ions was fabricated by using dimethylacetylamine (DMA), lithium perchlorate (LiClO4), and PVB. The experimental results indicated that a highly transparent GPE with a high ionic conductivity (σ) could be obtained by mixing glue (DMA with a PVB content of 10 wt%) with a LiClO4 content of 6 wt%. It was found that the ionic conductivity (σ) of the GPE depended on the LiClO4 content, and the GPE with a LiClO4 content of 6 wt% exhibited a maximum σ of 7.73 mS cm−1, a viscosity coefficient of 3360 mPa s, and a transmittance greater than 89% (visible region) at room temperature. Furthermore, PVB improved the electrolyte solution leakage, and the LiClO4 was used as an ion supply source for the high σ of the GPE.
