ELECTROLYTE GEL INCLUDING A POLYMER AND AN IONIC LIQUID, METHOD FOR PREPARING SAME AND USE THEREOF

摘要

The present invention relates to an electrolyte gel which includes: an ionic liquid of formula Z1X1, Z1 being a cation selected from the group including the imidazoliums, pyridiniums, cyclic ammoniums, acyclic ammoniums, and phosphoniums; and X1 being an anion selected from the group including bis(trifluorosulfonyl)imide (TFSI), bis(fluorosulfonyl)imide (FSI), hexafluorophosphate (PF6), tetrafluoroborate (BF4), iodide (I-), dicyanamide (DCA), and tetraborocyanide (B(CN)4); CL is a polymer network RP of at least one cross-linked polymer PCL; the cross-linked polymer PCL having at least: one repeat unit A, and one cross-linking unit UCL; the repeat unit A including a pendant chain Cp containing at least one cationic group Z2 in which the counterion X2 is selected from the group including bis(trifluorosulfonyl)imide (TFSI), bis(fluorosulfonyl)imide (FSI), hexafluorophosphate (PF6), tetrafluoroborate (BF4), iodide (I-), dicyanamide (DCA), and tetraborocyanide (B(CN)4); the cross-linked polymer PCL including 0.25 % to 40 % of the cross-linking unit UCL relative to the total number of A and UCL units; the weight ratio of PCL to Z1X1 ranging from 0.1 to 4.
