Document Type and Number:
WIPO Patent Application WO/2014/157125
Kind Code:
A1
Abstract:
A sodium secondary battery which comprises: a layer that contains a positive electrode active material that can be doped and undoped with sodium ions; a layer that contains a negative electrode active material that can be doped and undoped with sodium ions; an electrolyte that is capable of conducting sodium ions; and a collector. This sodium secondary battery comprises at least one collector that has such a structure wherein the layer that contains a positive electrode active material is laminated on one surface of the collector and the layer that contains a negative electrode active material is laminated on the other surface.
