ABSTRACT:
A storage battery of the lead-acid type has unipolar electrodes (6) and bipolar electrodes (7), having a tubular shape fastened preferably perpendicularly to walls (3, 4) made of an insulating material, which divide container into two or more adjacent cells (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 end plates (11, 12) of plastic material. The exteriorly extending ends (13), 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. The external bus bar (14) constitutes a pole of the storage battery.
