摘要
Raman spectroscopy was applied to investigate the intermolecular interactions in multi-component gel electrolytes consisting of ethylene carbonate and propylene carbonate, (EC-PC) mixed solvent, lithium salt and PMMA polymeric matrix. It is shown that triflate anions tend to essential aggregation in the EC/PC solvent, which results in a worsening of both mechanical and conductive properties of the gel. It is also found that PMMA-based gels with low salt concentration show an obvious macroscopic phase separation, and the spectroscopic characterization of the different phases is presented.
