Polymer ionogels are two-phase systems consisting of a solid polymer matrix and an ionic liquid trapped in it. Materials with good mechanical properties and high ionic conductivity have been used in electrochemical capacitors. Ionogels can be obtained by in-situ polymerization of monomers dissolved in an ionic liquid. Thiol-ene systems are interesting as polymer matrix precursors due to their insensitivity to oxygen, low polymerization shrinkage, and homogeneous polymer network formation. In this work ionogels that can be used in electrochemical capacitors as gel polymer electrolytes were obtained. These materials should becharacterized by high ionic conductivity (> 1 mS·cm–1) and mechanical resistance, especially during the operation or installation of electrochemical capacitors. In this study, ionogels with ionic conductivity above 1 mS cm–1 were obtained; therefore, they can be used as gel polymer electrolytes in electrochemical capacitors. Furthermore, these materials are characterized by good mechanical properties and can be twisted and rolled without suff ering damage.
