2. RESULT AND DISCUSSION
2.1. Influence of Li+ environment on degree of dissociation
To exploit polymers as dissociation enhancersfor advanced solid-state Li+ conductors, the polymer (originated from monomer) should be dispersed with Li salt for homogeneity and promoted intermolecular interaction between charged molecules. Taking these requirements into account, we rationally designed the structure of monomer (polymer precursors). The zwitterion(TFSI) was synthesized in two steps (Figure S1a). The potassium (3-chloropropylsulfonylperfluoroalkylsulfonyl)imide was by quaternized with N-(11-hydroxyundecyl)pyrrolidine to obtain
OH(TFSI). After, zwitterion(TFSI) was synthesized through the esterification reaction of acryloyl chloride and OH(TFSI)
