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.
A lead-acid storage battery, comprising a container for an electrolyte, the container being divided into a plurality of cells by at least one partition wall, the at least one partition wall being an insulating material and being transversed by bars of a conducting material, the bars supporting corresponding bipolar tubular electrodes, the container further having laterally extending end walls, the end walls being traversed by other bars, the other bars supporting corresponding unipolar tubular electrodes, the bipolar tubular electrodes and unipolar tubular electrodes being parallel to each other and being reciprocably interspersed, each of the at least one partition walls and the end walls have half walls which are coupled together to form the respective at least one partition wall and the end walls, the bars and the other bars each have a projection of a same material as the respective bar and other bar, the at least one partition wall and the end walls having cavities formed therein for receiving the projections, the cavities being formed by the half walls of the at least one partition wall and the end walls and the bars and the other bars being locked to the respective at least one partition wall and the end walls by the projections being received in the cavities.
The storage battery according to claim 3, wherein ends of the other bars for the unipolar tubular electrodes extend through the end walls of the container and wherein the storage battery further comprises a bus collector connected to the ends of the other bars outside the container, the bus collector constitutes a relative pole of the storage battery.
