Abstract: Disclosed are: a reinforced composite membrane-type polymer electrolyte membrane which can prevent the loss of an ion conductor even when the ion conductor is chemically deteriorated due to long-term use, and thus has remarkably enhanced mechanical and chemical durability; a method for manufacturing same; and an electrochemical device comprising same. The polymer electrolyte membrane of the present invention comprises: a non-crosslinked ion conductor; and a porous support having a plurality of pores filled with the ion conductor, wherein the porous support comprises a polymer having at least one crosslinking functional group, and the crosslinking functional group is a functional group which, when the ion conductor is deteriorated, can cause crosslinking of the ion conductor by binding to the deteriorated ion conductor.

Abstract: Disclosed are: a polymer electrolyte membrane which can prevent ionic conductor loss even upon the occurrence of chemical degradation in the ionic conductor according to long term use and thus can be significantly improved in chemical durability; a manufacturing method therefor; and an electrochemical device comprising same. The polymer electrolyte membrane of the present disclosure comprises a polymer electrolyte material. The polymer electrolyte material comprises an ionic conductor and a crosslinker unbound to the ionic conductor. The crosslinker has at least one cross-linkable functional group which can couple with the ionic conductor that has been degraded, thereby causing crosslinking with the ionic conductor.

Abstract: The present invention relates to an ion exchanging membrane, a method for manufacturing the same, and an energy storage system comprising the same. The ion exchanging membrane includes a porous support including a plurality of pores, a first ion conducting material located on one surface of the porous support, and a second ion conducting material located on the other surface of the porous support, in which the first ion conducting material and the second ion conducting material are polymers including hydrophilic repeating units and hydrophobic repeating units, and the first ion conducting material and the second ion conducting material have different molar ratios of the hydrophilic repeating units and the hydrophobic repeating units.According to the ion exchanging membrane, it is possible to improve overall efficiency of the energy storage system by improving both performance efficiency and voltage efficiency of the energy storage system due to excellent ion-conductivity performance and reduced membrane resistance and ensure durability of the energy storage system by having excellent morphological stability and reducing a crossover of vanadium ions.
