[Ion-conducting mechanism of composite polymer electrolyte: an emission FTIR spectroscopy study].
Solvent-free, composite electrolytes based on poly(ethylene oxide) (PEO) were prepared by using mesoporous silica SBA-15 with surface modification of (trimethylchlorosilane) as the filler. The samples were explored by emission FTIR spectroscopy at elevated temperatures. The results of emission FTIR spectra illustrated the dependence of crystalline PEO phase on temperature. On the basis of electrochemistry, SEM, and emission FTIR studies, the effect of inorganic filler on the ionic conductivity was analyzed, and a conclusion concerning the ion-conducting mechanism of composite polymer electrolyte was drawn. The exploratory experiments demonstrated that the emission FTIR spectroscopy is an important method to be applied in the study of lithium batteries.
