<P>PROBLEM TO BE SOLVED: To provide a manufacturing method of an electrode for a lithium ion battery and the electrode for the lithium ion battery in which, even when used as an electrode of the lithium ion battery using an electrolytic solution which does not contain a nitrile compound entirely, a material in which the electrolytic solution is hardly decomposed even at a potential with wide and high potential window and charge and discharge reach a region of high positive potential can be utilized as a positive electrode active material. <P>SOLUTION: The manufacturing method of the electrode for the lithium ion battery includes a dipping treatment process in which, before the electrode is made to contact an electrolytic solution of the lithium ion battery as a dipping treatment process, the electrode is immersed in a pretreatment electrolytic solution in which lithium salt is dissolved in an organic solvent containing nitrile compound of 10 vol% or more, and a positive voltage treatment in which the electrode is given positive voltage in the state immersed in the pretreatment electrolytic solution. <P>COPYRIGHT: (C)2011,JPO&INPIT |
