Description

Technical Field

[0001] This invention belongs to the field of tubular lead-acid battery technology, specifically relating to a low-energy-consumption curing and rapid activation tubular lead-acid battery and its preparation method. Background Technology

[0002] Currently, the commonly used production process for tubular positive electrodes is as follows: acid impregnation, curing and drying, assembly, and acid recycling. The acid impregnation time for the green positive electrode is 8-12 hours, and the acid density is 1.0-1.06 g / cm³. 3 The curing process involves a curing time of 24 hours, humidity control of 70-90%, and temperature of 30-50℃; a drying time of 48 hours and a temperature of 50-60℃; after curing and drying, internal formation charging is performed, with an internal formation time of 40-60 hours. This tube-type cathode production method has a long production cycle, high energy consumption, and low formation efficiency.

[0003] To reduce production energy consumption, shorten process time, and improve industry competitiveness, it is necessary to study a new method for preparing tubular lead-acid batteries. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a method for preparing a tubular lead-acid battery with low energy consumption curing and rapid activation, which effectively reduces the energy consumption in battery preparation and shortens the product preparation time; the present invention also provides a tubular lead-acid battery prepared therefrom with improved initial performance.

[0005] The method for preparing the low-energy-consumption curing and rapid-activation tubular lead-acid battery of the present invention includes the following steps:

[0006] (1) Acid impregnation of the positive electrode plate: The positive electrode plate is impregnated using a hot-temperature alternating impregnation method. First, it is impregnated in an acid impregnation tank at 45~50℃ for 10~15s, and then impregnated in an acid impregnation tank at 25~30℃ for 15~20s. The acid density is 1.10~1.15g / cm³. 3 ;

[0007] (2) Curing and drying of positive electrode plates: The acid-impregnated positive electrode plates are placed in a closed space in a staggered stacking manner for natural curing. The curing time is 10~12h to obtain the positive electrode plate.

[0008] (3) Curing and drying of negative electrode plate: First, cure the negative electrode plate at a humidity of 95~100% for 8~10h, then cure it at a humidity of 70~75% for 10~12h, and finally dry it at 70~80℃ for 10~12h to obtain the negative electrode plate;

[0009] (4) Assembly: Assemble the positive and negative plates into an electrode group and place it in the slot. Heat-seal the battery case cover, press in the sealing ring, and close the liquid filling cap.

[0010] (5) Formation: The assembled battery is first charged with constant voltage at 2.4V for 10-12 hours, and then charged with constant current at 0.05C5 for 10-12 hours to obtain a tubular lead-acid battery.

[0011] In step (1) of this invention, the positive electrode material is mixed evenly and a positive electrode plate is prepared by a powder filling method.

[0012] In step (1) of the present invention, the positive electrode material comprises 5 to 10 parts of lead powder and 90 to 95 parts of lead tetroxide by weight.

[0013] In step (1) of this invention, the apparent density of the active material in the positive electrode plate is 4.05~4.15 g / cm³. 3 .

[0014] (3) The present invention uses a constant temperature precision acid soaking tank during acid soaking. Before acid soaking, the acid density of the two acid soaking tanks is kept constant after conversion. The temperature of the first acid soaking tank is kept constant at 45~50℃ and the acid soaking time is 10~15s. The active material composition structure is changed by short-time high temperature acid soaking. The temperature of the second acid soaking tank is kept constant at 25~30℃ and the acid soaking time is 15~20s. After acid soaking, the inside of the positive electrode plate is paste-like and a shallow layer of lead sulfate is formed on the surface of the active material.

[0015] In step (2) of this invention, a closed space is used for curing, and the plates are stacked in a staggered manner. The temperature of the closed space is not lower than 30°C. During the curing process, oxygen in the air, as well as heat released by the positive electrode and moisture, are gradually evaporated to form corrosion and oxidation reactions.

[0016] In step (3) of this invention, negative electrode material is added to the paste mixing machine and adjusted with pure water to an apparent density of 4.25~4.35 g / cm³. 3 Lead paste is made and applied to the negative plate grid to form the negative electrode plate.

[0017] In step (3) of the present invention, the negative electrode material includes 80-82 parts of lead powder, 13-15 parts of H2SO4 solution, 0.01-0.03 parts of barium sulfate, 0.05-0.08 parts of humic acid and 0.05-0.08 parts of polypropylene fiber.

[0018] This invention employs a multi-stage curing method to cure the negative electrode plate. The first stage is a high-humidity curing stage, the second stage is a curing strengthening stage, and then a high-temperature rapid drying method is used to dry the negative electrode plate, which can effectively shorten the curing and drying time and reduce energy consumption.

[0019] In step (5) of the present invention, the total charging time is 22~24h and the total charging capacity is 5.5~6.0C5.

[0020] The positive and negative plates of this invention are manufactured using a special process, which enables the battery to have high charging efficiency, fast plate conversion rate, and significantly shortened charging time when charged with high current.

[0021] This invention also provides a tubular lead-acid battery prepared by the above-described method. Compared with the prior art, the advantages of this invention are as follows:

[0022] (1) The present invention adopts a low-energy consumption and rapid curing production method. Under constant density and constant temperature, the acid immersion time of the positive electrode green plate is only 20s. Only a lead sulfate layer is generated on the outer surface of the electrode plate. After the acid immersion is completed, it is quickly put into a closed space for natural curing and drying. The oxygen in the air and the heat released by the electrode plate form an oxidation reaction, which shortens the electrode curing time. After curing, a multi-stage constant voltage charging method is used for formation, which also greatly shortens the formation time. This production method greatly shortens the process time of acid immersion, curing and formation. After adopting the low-energy consumption curing method, the process time is shortened by 70% and the energy consumption is reduced by 60%. While improving production efficiency, the energy saving and emission reduction effect is obvious.

[0023] (2) The preparation process of the present invention can effectively reduce the energy consumption of battery preparation, shorten the battery production cycle, and achieve efficient and stable conversion while meeting product performance requirements. Detailed Implementation
