Novel onium salt, electrolyte for non-aqueous cell containing the novel onium salt for nonaqueous cell, and method for optimizing negative electrode using elecrolyte containing onium salt |
摘要 |
There are provided a novel onium salt and a method for optimizing the interface of a negative electrode by the use of the novel onium salt and/or a conventional onium salt. Such a method is characterized in that an electrolyte comprising novel 2,2,2-trifluoro-N-(trifluoromethanesulfonyl) acetamide.tetraethyl ammonium salt is made to intervene between a negative electrode and a positive electrode in an electrochemical device having the constitution: a negative electrode | an electrolyte | a positive electrode, thereby constructing an electrode structure in the electrochemical device, and applying a voltage between the negative electrode and the positive electrode so as for the negative electrode to have a potential of -1 V to -5 V in terms of the potential relative to a reference electrode of I<->/I<3->, thereby forming a passive-state layer comprising a decomposition product of the above electrolyte or salt on the surface of the above negative electrode.
