Abstract
The invention provides a high-temperature paste mixing process for prolonging the cycle life of a battery, which comprises the following steps of: adding 75 to 90 DEG C deionized water, adding short fibers and an anode additive, and stirring for 5 to 7 minutes; adding lead powder and stirring for 10 to 12 minutes; and slowly adding dilute sulfuric acid, stirring for 8 to 10 minutes, finishing paste mixing, and discharging paste when the temperature is lower than 45 DEG C. By the process, the cycle life of a valve-regulated lead-acid storage battery formed by assembling an anode plate produced by the paste mixing process is greatly prolonged, and the stability is greatly improved.
Description
Technical field
The present invention relates to the storage battery field, be specifically related to a kind of high temperature and cream technique that improves battery cycle life.
Background technology
At present, the domestic overwhelming majority is produced the producer of valve-regulated lead-acid battery pole plate when producing positive plate, all adopts normal temperature and cream technique, but cycle life this and the valve control lead-acid storage battery anode plate that cream technique is produced is not fully up to expectations.Dissect discovery through the battery that cycle life finishes, the positive plate lead plaster is softening to be the main cause that battery life finishes.By the inquiry related data, the tribasic lead sulfate (3BS) of four basic lead sulphates (4BS) of big crystal grain and less crystal grain is separately converted to corresponding α-PbO through after changing in the lead plaster
2And β-PbO
2, α-PbO
2(α-brown lead oxide) content height, β-PbO
2The battery cycle life of the positive plate assembling that (β-brown lead oxide) content is low is long, that is to say and will obtain more 4BS in lead plaster is formed, and can increase the cycle life of positive plate.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of high temperature and cream technique that improves battery cycle life, can make the cycle life and the stability of the valve-regulated lead-acid battery that the positive plate that utilizes this and cream technique production is assembled into improve greatly.
For solving above-mentioned existing technical problem, the present invention adopts following scheme: a kind of high temperature and cream technique that improves battery cycle life, at first add 75～90 ℃ deionized water, adding short fiber and anode additive then stirred 5～7 minutes, then adding lead powder stirred 10～12 minutes, slowly add dilute sulfuric acid at last again and stirred 8～10 minutes, finish and cream, treat that temperature is lower than 45 ℃ and goes out cream.
As preferably, at first add 75 ℃ deionized water, add short fiber and anode additive then and stirred 5 minutes, then add lead powder and stirred 10 minutes, slowly add dilute sulfuric acid at last again and stirred 8 minutes, finish and cream, treat that temperature is lower than 45 ℃ and goes out cream.
As preferably, at first add 80 ℃ deionized water, add short fiber and anode additive then and stirred 6 minutes, then add lead powder and stirred 11 minutes, slowly add dilute sulfuric acid at last again and stirred 9 minutes, finish and cream, treat that temperature is lower than 45 ℃ and goes out cream.
As preferably, at first add 90 ℃ deionized water, add short fiber and anode additive then and stirred 7 minutes, then add lead powder and stirred 12 minutes, slowly add dilute sulfuric acid at last again and stirred 10 minutes, finish and cream, treat that temperature is lower than 45 ℃ and goes out cream.
Beneficial effect:
The present invention adopts technique scheme that a kind of high temperature and cream technique that improves battery cycle life is provided, and can make the cycle life and the stability of the valve-regulated lead-acid battery that the positive plate that utilizes this and cream technique production is assembled into improve greatly.
Description of drawings
Fig. 1 is for adopting lead plaster crystallization schematic diagram existing and that cream technique forms;
The lead plaster crystallization schematic diagram of Fig. 2 for adopting the present invention to form.
Embodiment
Embodiment one:
