Embodiment 1

[0035] Embodiment 1, is a basic embodiment of the present invention. A method for internalizing lead-acid storage batteries for plate-type traction, comprising the following steps:

[0036] 1) The preparation temperature is 5-15°C and the density is 1.240-1.270g / cm 3 sulfuric acid solution;

[0037] 2) Place the battery in a water bath and cool it with tap water circulation;

[0038] 3) Inject the cooled sulfuric acid solution, let it stand for 2 to 3 hours, and start charging when the temperature is lower than 45°C;

[0039] 4) Internalization process.

Embodiment 2

[0040] Embodiment 2, is a further embodiment of embodiment 1. Different from Example 1: the internalization process includes the following six stages:

[0041] The first stage: 0.3I 5 ~0.5I 5 Charge for 2 to 4 hours;

[0042] The second stage: 0.9I 5 ~1.1I 5 Charging for 30-40 hours;

[0043] The third stage: stand still for 2-4 hours, add water 500-700mL;

[0044] The fourth stage: 0.9I 5 ~1.1I 5 Charging for 12-16 hours;

[0045] The fifth stage: stand still for 2-4 hours, add 400-600mL of water;

[0046] Sixth stage: 0.5I 5 ~0.8I 5 Charging for 2 to 4 hours,

[0047] Among them, I 5 Indicates the discharge current of the battery at a rate of 5 hours.

Embodiment 3

[0048] Embodiment 3, It is an optimized embodiment of the present invention. A kind of 2V400Ah lead-acid storage battery for traction, the internal formation method steps and internal formation process under the weather with temperature of 10°C are as follows:

[0049] Place the battery in a water bath, cool it with tap water circulation, and connect the charging line of the lead-acid battery. Set the density to 1.250g / cm 3 1. Cool the sulfuric acid solution with a temperature of 30°C to a temperature of 10°C. Inject about 5.6kg of cooled sulfuric acid solution. After standing still for 2 hours, the temperature was 38°C. Turn on the charger for charging as follows:

[0050] (1) Charge at 30A for 2 hours; (2) Charge at 75A for 35h; (3) Stand still for 2h, add water 650mL; (4) Charge at 75A for 15h; (5) Stand still for 2h, add water 500mL; (6) Charge at 50A Charge for 4 hours to make the electrolyte uniform. The total synthesis time is 60h.

[0051] According to GB / T704...

Abstract

The patent of the present invention relates to a method for the internalization of lead-acid batteries for plate traction, including the following steps: 1. Prepare a sulfuric acid solution with a certain temperature and density; 2. Place the battery in a water bath and cool it with tap water; 3. The sulfuric acid solution is left to stand for a period of time, and starts charging when the temperature is lower than a certain temperature; 4. Internalization process. The internalization process is divided into six stages, including four stages of charging and two stages of standing still and adding water. The invention has the advantages of greatly shortening the production cycle, simplifying the production process, improving the initial capacity, high-rate discharge and cycle durability of the storage battery, and having good environmental effects during the production and operation of the storage battery.

Description

Technical field [0001] The present invention involves lead -acid batteryization into a field, and specifically involves the internalization method of a plate traction with a lead -acid battery. Background technique [0002] The ingredients of lead -acid batteries are internalized (batteryized) and externalization (grooves).Among them, the externalization is used to use the specialized tank with dilute sulfuric acid electrolyte to complete the process of turning the polar plate.The internalization is to assemble the curing and dry -to -day plate into a battery, and inject the charging method of the electrolytic solution after being configured. [0003] The internalization of the battery is the advantage of the complex process of the raw pole plates into a slot into a slot, as well as the process of washing, drying and drying after the formation, and simplified the process, which is easier to achieve mechanized production.Its production efficiency, short production cycle, low labor...
