Gel electrolyte composite including ionic liquid and zwitterionic polymer scaffold
A gel electrolyte composite containing a nonvolatile electrolyte and a zwitterionic polymer scaffold in which the non-volatile electrolyte is a non-lithium-containing ionic liquid, a sodium-containing ionic liquid, or a lithium-containing ionic liquid and the zwitterionic polymer scaffold is formed from one or more zwitterionic monomers only or both one or more zwitterionic monomers and one or more non-zwitterionic monomers. The zwitterionic polymer scaffold contains 8 mol % or higher of zwitterions relative to the total content of the gel electrolyte composite when the nonvolatile electrolyte is a non-lithium-containing ionic liquid, and contains 1 mol % or higher of zwitterions relative to the total content of the gel electrolyte composite when the nonvolatile electrolyte is a sodium-containing ionic liquid or a lithium-containing ionic liquid. Also disclosed are a method of preparing the above-described gel electrolyte composite and an electrochemical energy storage device containing same.
