摘要: Abstract Both lithium bromide (LiBr) and biosynthesized silver nanoparticles (Ag NPs) with average size 2–30 nm have been incorporated into the polymeric matrix of polyethylene oxide polyacrylamide (PEO/PAM) blend by casting method. FT-IR analysis indicates formation hydrogen bond between components. Also, LiBr Ag NPs interact functional groups PEO/PAM matrix. The results XRD depict semi-crystalline nature these polymer samples degree crystallinity is decreased due to addition process. values optical energy gap from UV–Vis. data are 3.55 eV for 3.26 nanocomposite sample in indirect transition. LiBr/Ag assist improvement thermal stability blend, as evidenced TGA DTA techniques. Upon NPs, an conductivity, dielectric permittivity (έ) loss (ἕ) solid electrolytes observed. It's clear that electrical conductivity parameters PEO/PAM: Li+/Ag electrolyte system makes it a promising candidate solid-state Li battery applications.
