The invention relates to the technical field of chemical power supply materials, in particular to a continuous solderless lead-acid
battery electrode group and a manufacturing method thereof. The continuous solder-free lead-acid
battery electrode group comprises a continuous positive
electrode plate, a continuous negative
electrode plate, a cross-unit connecting piece, a continuous bipolar
electrode plate and a separator, wherein the continuous bipolar electrode plate is composed of a continuous positive electrode plate, a continuous negative electrode plate and a separator which are insertedand matched. A lead storage
battery electrode group is integrally and continuously design, and that
welding procedure of a plurality of positive plate or negative plates in the electrode plate group in the production process of the storage battery is eliminated, and the series and parallel
welding procedures such as cross-bridge
welding and through-wall welding between a plurality of monomers of the storage battery are also eliminated. This not only reduces the lead consumption of the battery, but also does not appear the phenomenon of chips falling off and missing welding between the electrode plate group and the
monomer of the battery, which effectively improves the product quality and reliability of the battery. In addition, the electrode group of the invention has high manufacturing
process efficiency and is convenient for production and
processing.
