description A storage battery of the lead-acid type is disclosed, comprising unipolar electrodes (6) and bipolar electrodes (7), having a tubular shape fastened preferably perpendicularly to separators (3, 4) made of an insulating material, which divide into two or more adjacent cells the container (1) containing the electrolyte. In a preferred embodiment, each tubular electrode (6, 7) is formed by an axial bar (8) of lead or an alloy thereof, having a circular section, surrounded by active material (9), either positive or negative, in its turn enclosed by a coaxial tubular sheath (10) in porous synthetic and insulating material, and plugs (11, 12) of plastic material. The ends (13), brought to the exterior, of the bars (8) of the unipolar tubular electrodes (6) of each of the end cells are connected to a respective external bus bar (14) for the current, constituting a pole of the storage battery (figure 2).
