Zwitterionic additives for electrochemical devices

Zwitterionic electrolytes such as N-methyl-N-(n-butanesulfonate) pyrrolidinium are added to electrolyte compositions such as polyelectrolytes, ionic liquid electrolytes and molecular solvent electrolytes (for example, lithium hexafluorophosphate) to improve conductivity of the ion species, such as l...

Beschreibung
Zusammenfassung:	Zwitterionic electrolytes such as N-methyl-N-(n-butanesulfonate) pyrrolidinium are added to electrolyte compositions such as polyelectrolytes, ionic liquid electrolytes and molecular solvent electrolytes (for example, lithium hexafluorophosphate) to improve conductivity of the ion species, such as lithium, in the electrolyte. This has application to lithium based energy storage devices such as batteries and supercapacitors.
