Abstract
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.
Claims5
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 more elements
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.
