A comparative study of the influence of TiO
2
and SiO
2
nanoparticles on the physicochemical properties of nanocomposite polymer electrolytes (NPEs) based on polyethylene glycol diacrylate, the LiBF
4
salt, the ionic liquid 1-ethyl-3-methylimidazolium tetrafluoroborate (EMIBF
4
), and ethylene carbonate has been carried out. The stability of NPE films was studied by thermogravimetric analysis, the distribution of nanoparticles and ions was determined by Raman spectroscopy and microscopy, and conductivity was measured using the electrochemical impedance method. It has been shown that SiO
2
-based NPEs have the best thermal stability and conductivity characteristics.
