Lithium ion secondary cell and manufacturing method thereof |
| abstract |
Disclosed is a lithium ion secondary battery wherein an active material layer of at least one of positive and negative electrodes, or a separator carries a porous insulating layer, and the surface of the active material layer or separator carrying the porous insulating layer has a first region in which the porous insulating layer is formed and a second region including plural discontinuous deficient hole portions where the porous insulating layer is not formed. When a given reference deficient hole portion is selected from the plural deficient hole portions and a given circle having an area ten times that of the reference deficient hole portion is set on the surface of the active material layer or separator, the area of a part of the second region surrounded by the circle is controlled to not less than 10 µm 2 and not more than 100 mm 2 . |
