The invention relates to a solid polymer electrolyte comprising a eutectic mixture comprising a fluorinated salt and an organic compound forming a eutectic mixture with said fluorinated salt. This solid polymer electrolyte can be obtained by polymerization and/or crosslinking of a composition comprising a eutectic mixture comprising a fluorinated salt and an organic compound forming a eutectic mixture with said fluorinated salt and a polymerizable and/or crosslinkable compound. In addition, the invention also relates to a process for producing said solid polymer electrolyte and to the uses thereof as an electrolyte in an electrochemical device, in particular as an electrolyte in a battery or in an electronic display device, in particular an electrochromic device.
