<P>PROBLEM TO BE SOLVED: To provide an all-solid lithium ion battery exhibiting excellent cycle characteristics in which an electrode layer is not detached nor cracked even if charge/discharge is repeated, and to provide an all-solid lithium ion battery having good rate characteristics in which an ion conduction path or an electron conduction path is formed well. <P>SOLUTION: In the all-solid lithium ion battery, an inorganic solid electrolyte layer is laminated between the electrode layers of positive electrode and negative electrode, and either the positive electrode layer and/or the negative electrode layer has a porosity in the range of 5-50%. <P>COPYRIGHT: (C)2012,JPO&INPIT |
