Abstract
To provide a method that is capable of suppressing absorption of lithium ions into the inner portion of a resin collector that is used in a bipolar lithium ion secondary battery. The collector for a bipolar lithium ion secondary battery of the invention has at least two conductive layers. One of the conductive layers that constitute the collector (a first conductive layer) is configured by adding a conductive filler into a base material that contains an imide group-containing resin. The other of the conductive layers that constitute the collector (a second conductive layer) is configured by adding a conductive filler into a base material that contains a polar resin containing no imide group. The collector for a bipolar lithium ion secondary battery is further characterized in that when a bipolar electrode is formed, the first conductive layer is arranged on the positive electrode side.
