Abstract

The invention discloses a tubular lead-acid storage battery, a tubular electrode of the battery is obtained by a certain manufacturing method, and the manufacturing method comprises the following steps that: by mechanical acting force, a tubular electrode with a cambered surface, such as a circular tubular electrode or/and a porous tube with a cambered surface of the tubular electrode or/and the shape of the radial section of an active substance in the tube are deformed; wherein the deformation comprises, but is not limited to, deforming the cambered surface into more than one plane and deforming the radial cross section shape into a radial cross section shape with a straight edge, and the method is also a manufacturing method of the tubular lead-acid storage battery disclosed by the invention; according to the tubular lead-acid storage battery, the tubular electrode and the manufacturing method thereof, the volumetric specific energy of the tubular lead-acid storage battery is improved, the contact area between the surface of the tubular electrode and the surface of a partition plate is increased, the tight assembly of the tubular lead-acid storage battery is facilitated, a gas transmission channel is formed between a positive electrode and a negative electrode, and the tubular lead-acid storage battery is manufactured into a valve-controlled and maintenance-free battery.

Description

technical field [0001] The invention relates to a lead-acid battery, in particular to a tubular lead-acid battery and a manufacturing method thereof. Background technique [0002] Tubular lead-acid batteries currently use round tube electrodes, and some use oblate and oval tube electrodes. These electrodes have arc-shaped surfaces, which makes it easier to assemble these tube electrodes with arc-shaped electrode surfaces into batteries. A larger gap is generated between the electrodes, resulting in a larger volume of the battery or a smaller volume specific energy; The surface does not coincide well with the plane of the planar sheet separator, which is not conducive to the tight assembly of the battery, the formation of gas transmission channels between the positive and negative electrodes, and the fabrication of valve-controlled and maintenance-free batteries. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a ...
