摘要: Abstract The results of a preliminary investigation series polymer electrolytes based on novel host, poly(trimethylene carbonate) (p(TMC)), with lithium triflate or perchlorate and various plasticizing additives, are described in this presentation. Electrolytes salt compositions about n =10 (where represents the molar ratio (OCOCH 2 CH O) units per ion) additive between 5 15 wt.% (with respect to p(TMC)), were prepared by co-dissolution anhydrous solvent controlled amount additive. homogeneous solutions obtained evaporated within preparative glovebox under dry argon atmosphere form thin films electrolyte. solvent-free electrolyte produced characterized measurements total ionic conductivity, differential scanning calorimetry thermogravimetry. In general triflate-based found show moderate conductivity good thermal stability while perchlorate-based showed higher levels but lower stability. host polymer, both salts, as very flexible, transparent, completely amorphous films.
