Synthesis and Use of Zwitterion Bearing Sulfonyl(trifluoromethane sylfonyl)imide Anion as Additive for Polymer Electrolytes
In order to improve the electrochemical properties of poly(ethylene oxide), a well-known-solid polymer electrolyte, by adding zwitterion molecules, the synthesis of a new zwitterion (<b>ZN</b>) having imidazolium cation and sulfonyl(trifluoromethane sulfonyl)imide anion is investigated....

| description | In order to improve the electrochemical properties of poly(ethylene oxide), a well-known-solid polymer electrolyte, by adding zwitterion molecules, the synthesis of a new zwitterion (<b>ZN</b>) having imidazolium cation and sulfonyl(trifluoromethane sulfonyl)imide anion is investigated. The addition of different amounts of <b>ZN</b> to the mixture of lithium bis(trifluoromethane sulfonyl)imide (LiTFSI) and poly(ethylene glycol)dimethyl ether (PEGDM) of 1000 g mol<sup>−1</sup> does not significantly affect the transition temperature of PEGDM but causes a slight decrease in ionic conductivity of the electrolyte mixtures. However, even with the presence of only 0.05 mole fraction of <b>ZN,</b> the anodic stability of LiTFSI/PEGDM based electrolytes is improved to over 4.5 V vs. Li<sup>+</sup>/Li at 25 °C. This makes the new synthesized zwitterion a promising electrolyte’s additive for high voltage batteries. |
