Description

Technical Field

[0001] The invention relates to the technical field of lead-acid battery production, in particular to an acid circulation formation cooling system for a tubular flooded power battery. Background Art

[0002] Lead-acid battery is an acidic battery with lead dioxide as the positive electrode, spongy lead as the negative electrode, and sulfuric acid aqueous solution as the electrolyte.

[0003] The advantages of lead-acid batteries include high operating voltage, wide operating temperature range, good high and low rate discharge performance, abundant raw material sources, low price, strong high current discharge performance, stable voltage characteristics, and high safety. However, its disadvantage is low energy density, resulting in larger volume and weight, small specific energy, and strong corrosiveness to the environment.

[0004] In today's acid circulation of flooded batteries, the electrolyte cooling system used is mostly air cooling. During the heat exchange between cold air and electrolyte, part of the acid will inevitably be taken away to form sulfuric acid mist, which increases the burden of acid mist purification in the later stage, increases energy consumption, and brings greater environmental pollution. At the same time, the effect of air cooling is poor. During the formation and charging process, the electrolyte temperature is easy to rise and is difficult to control, resulting in poor conversion of the active material structure during the battery formation process, affecting the battery life.

[0005] Therefore, we propose a tubular flooded power battery acid circulation formation cooling system. Summary of the invention
