An energy storage device is provided that includes a bipolar conductive substrate having a first side coupled to a first substack and a second side coupled to a second substack. The first and second substacks have a plurality of alternately stacked positive and negative monopolar electrode units. Each respective monopolar electrode unit has a first and second active material electrode layer on opposing sides of a conductive pathway. A separator is provided between adjacent monopolar electrode units. The conductive pathways of the positive monopolar electrode units are electronically coupled to form a positive tabbed current bus, and the conductive pathways of the negative monopolar electrode units are electronically coupled to form a negative tabbed current bus. The negative tabbed current bus of the first substack and the positive tabbed current bus of the second substack are coupled to the first and second side of the bipolar conductive substrate respectively.
