摘要: Solvent-free, composite electrolytes based on poly(ethylene oxide) (PEO) have been prepared by using LiClO4 and LiN(CF3SO2)2 as the doping salts, nanoscale SiO2 filler. The samples characterized for what concerns their thermal transport properties. addition of filler determines an increase conductivity more than one order-of-magnitude, depending concentration. maximum value 1.4×10−4 ohm−1 cm−1 is obtained sample PEO8–LiN(CF3SO2)2–5 wt% SiO2. Effects silica history level also ascertained. cation number, t+, changes from ~0.1 to ~0.2 when 10 added.
