The capacity size of the lead-acid battery determines the working time, the amount of lead, determines the deep cycle ability of the battery, and adds a battery that is different than the heavy electrolyte, the initial capacity, the national standard circulating life and different constant flows The cycle life test under pressure charging control, and anatomical analysis of the cycle life termination battery, the following conclusions: the battery polar plate is weighted, the lower the specific gravity of the electrolyte, the lower the battery, especially the large current discharge Performance is more pronounced, but the battery life is significantly extended. For batteries having a large weight of the electrolyte, the constant current limiting charge is reasonably selected, and the negative electrode sulfate and positive muddylation of the battery can be avoided, and the battery cycle life can be avoided.The life of the lead-acid battery is terminated due to insufficient capacity, and for the battery, its cycle life is a key indicator in its numerous indicators. For valve-controlled lead-acid batteries, the recognition measures of extending battery cycle life is to increase long-term additives in the lead paste formula, using high tube low calcium alloy, high temperature solidification, improve assembly pressure, and so on. But even all the above measures are taken, the production of battery life does not necessarily meet the level of battery life.
In particular, with the increase of cost pressure, in order to reduce production costs, improve the production cost, improve the battery's large current discharge performance, and constantly reduce the thickness of the battery and increase the specific gravity of the electrolyte, this for the overall performance of the battery, especially The cycle performance is undoubtedly a method of killing chicken to take ovate. Battery manufacturing uses 3 positive 4 negative (the positive electrode thickness of 3.6 mm), and the 4 positive 5 negative (the positive electrode thickness is 2.8 mm), the plate is a slot formation process, and the battery is assembled and 1.27, 1.29, respectively. 1.31, 1.33 four specific gravity electrolytes, the amount of effective acid in the amount of the acid is the same.
The battery is tested after the process is completed, the battery weight and internal resistance are tested. The weight of the two structural batteries is about 2.60 kg and 2.45 kg, respectively, and the internal resistance is about 19 mΩ and 17 mΩ, respectively. The initial capacity of various batteries and two cycle life are then tested. By the initial capacity of the lead-acid battery of different electrode plate thickness, the specific gravity of different electrolytes, the constant current limit of the national standard cycle life, the constant current limit of different pressure limits to the battery cycle life, and the anatomical analysis of the life of the battery, Conclusion: Suitable increase the thickness of the positive electrode plate, reducing the specific gravity of the electrolyte, selecting the best constant current limit charging, and can improve the cycle life of the battery.
