在对有机锂盐的持续研究中，我们发现酰亚胺盐(RfSO2)(R′fSO2)NLi在有机溶剂中表现出高电导率，并且酰亚胺盐的改性改变了铝集流体的阳极氧化电位和溶解电位。具有长氟烷基的酰亚胺锂（如 (C4F9SO2)(CF3SO2)NLi 和新型酯型酰亚胺盐 ((CF3)2CHOSO2)2NLi 分别在高达 4.8 和 4.3 V 时不会溶解铝捕收剂。我们还研究了酯型酰亚胺盐的聚合物类似物，例如(-CH2(CF2)4CH2OSO2N(Li)SO2O-)9–10。
In our continuous study on organic lithium salts, we found that the imide salt (RfSO2)(R′fSO2)NLi shows high conductivity in organic solvents, and that the modification of the imide salts change the anodic oxidation potential and the dissolution potential of aluminum current collector. Lithium imide with long fluoroalkyl groups such as (C4F9SO2)(CF3SO2)NLi and the new ester-type imide salts, ((CF3)2CHOSO2)2NLi do not dissolve the aluminum collector up to 4.8 and 4.3 V, respectively. We also examined the polymer analogue of the ester-type imide salt such as (-CH2(CF2)4CH2OSO2N(Li)SO2O-)9–10.
