Abstract
Official abstract text for this publication.
The present disclosure relates to a solid-state polymer electrolyte with improved processability and a method for manufacturing the same, and more particularly to a solid electrolyte containing a polymer obtained by pertaining polymerization of a zwitterionic monomer in a solvent-free ionic liquid.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for manufacturing a solid electrolyte, the method comprising: mixing sulfobetaine methacrylate with an ionic liquid; and polymerizing the sulfobetaine methacrylate in the ionic liquid; wherein the sulfobetaine methacrylate and the ionic liquid are mixed at a weight ratio of 1:0.3 to 1:2, wherein the ionic liquid is 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide. 2. The method of claim 1 , wherein no solvent is added in the mixing the sulfobetaine methacrylate and the ionic liquid. 3. The method of claim 1 , further comprising applying the mixed sulfobetaine methacrylate and ionic liquid to an object prior to the polymerizing of the mixture. 4. A solid electrolyte comprising a polymer obtained by a polymerization of a sulfobetaine methacrylate and an ionic liquid in the absence of solvent, wherein a weight ratio of the polymer to the ionic liquid is 1:0.3 to 1:2, and there is no solvent in the solid electrolyte, and the solid electrolyte is present in a supercapacitor; and wherein the ionic liquid is 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide. 5. A supercapacitor comprising the solid electrolyte of claim 4 .
