A novel flexible carbon article for an electrode is disclosed use in an electrical storage device is disclosed in which the flexible carbon article, such as a planar sheet of a plurality of substantially parallel fibers or ribbons, has a Young's modulus of less than IMM psi (6.89 Gpa). The invention also resides in an electrical energy storage device, such as a secondary battery, comprising a water impermeable housing having at least one and preferably more than two cells in series, wherein a battely containing at least two cells also contains at least one shared bipolar electrode made of the flexible carbon article. Each cell has a foraminous separator between each pair of electrodes and contains an electrolyte comprising an ionizable salt in a non-aqueous fluid. Also disclosed are methods of making the electrode from an unfiltered precursor polymer and from a sub-acrylic polymer
