A gel polymer electrolyte based on a novel synthesized matrix of a self-doped polymer of h-poly(methyl methacrylate-vinyl trismethoxy silane)

摘要: In order to incorporate inorganic nano-particles into a gel polymer electrolyte (GPE) in the form of chemical bonds improve performances, monomers methyl methacrylate (MMA) and vinyl trismethoxy silane (VTMS) were chosen synthesize novel self-doped h-poly(methyl methacrylate-vinyl silane) (h-P(MMA-VTMS)), then obtained was used as matrix prepare GPE. By characterization resultant polymer, composition structure conformed design concept, is amorphous possesses two different glass transition temperatures (Tg) better thermal stability. From investigation prepared GPE, it thermally stable temperature range from 30 °C 100 ionic conductivity reaches level 10−4 S cm−1 at room temperature. For 50 wt% GPE system, variation displays an Arrhenius behavior 60 °C. The higher lithium ion transference number 0.42, compatibility with metal anode electrochemical stability up 5.2 V versus Li/Li+.
