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 ...
