Description
Technical Field
The invention relates to the technical field of storage batteries, in particular to a nano regenerative repairing agent for a storage battery and a preparation method thereof.
Background
The lead-acid storage battery is a storage battery with electrodes mainly made of lead and lead oxide and sulfuric acid as electrolyte, is simple to maintain, long in service life, stable in quality, safe and reliable, and is widely applied to multiple industries such as telecommunications, electric power, machinery and the like. Generally, the service life of a lead storage battery is 10-15 years, although the lead storage battery has a long service life, the service life of the lead storage battery can be influenced by a plurality of factors such as the discharge depth, the overcharge degree, the temperature and the sulfuric acid concentration, and the condition that the battery is scrapped when the service life is not reached is caused. Among many factors, the crystallization and salinization of lead sulfate of a negative plate material are the main factors for scrapping the storage battery, and account for more than 90 percent of the reasons for early scrapping of the lead-acid storage battery. In order to solve the above problem, methods adopted in the prior art include large-current charging repair, high-frequency pulse repair, tandem repair, negative pulse repair, and the like, but such methods generally have various problems, such as easy damage to the electrode plate and difficulty in deeply removing sulfuric acid crystals, and the like, and therefore, a repair method capable of deeply repairing the electrode plate without or with less damage to the electrode plate is needed. In recent years, some researchers have conducted research on a repair agent to more effectively solve the problem of regeneration of a secondary battery.
Chinese patent CN109830767A discloses an environment-friendly lead-acid storage battery nano repairing agent and a preparation method thereof, and the repairing agent comprises, by weight, 1-10 parts of polystyrene water-based chelating polymer, 1-15 parts of polyoxyethylene polyoxypropylene modified dimethyl siloxane polymer, 1-6 parts of sulfate, 1-8 parts of nanoparticle additive and 62-95 parts of deionized water. The repairing agent can form a molecular self-arrangement protective film on a battery pole plate, prevents lead sulfate crystals from being attached to the pole plate again, efficiently solves the vulcanization phenomenon, and has the characteristics of convenient use, stable performance, safety, no toxicity and the like, and high repairing rate. However, the preparation process of the repairing agent in the invention involves melting of materials such as polymers, and the like, and may consume more energy and increase the energy consumption burden.
Chinese patent CN103700898B discloses a lead-acid storage battery repairing agent and a preparation method thereof, the preparation method comprises the steps of adding a hydrogen evolution inhibitor into sulfuric acid with the pH value of 4-6, stirring to form a transparent solution, adding high-conductivity nano carbon particles, and stirring to form a semitransparent suspension to obtain the lead-acid storage battery repairing agent. The method is simple and easy to implement, the raw materials are cheap and the source is wide, and the prepared lead-acid storage battery repairing agent slows down the sulfation rate and prolongs the service life of the battery; meanwhile, the charging and discharging rate of the battery can be improved, the utilization rate of active substances is improved, and the capacity of the battery is improved. However, the hydrogen evolution inhibitor in the patent contains dodecylbenzene sulfonic acid, which may cause problems of water pollution and the like if the hydrogen evolution inhibitor is not properly treated in the preparation process or when batteries are discarded, and meanwhile, the repairing agent may face a short board in the aspect of protection of subsequent tissue lead sulfate crystals.

The only difference from example 3 is that the nanoparticles are nanocarbon, nanotitania and nanosilica in a weight ratio of 0.2:3:1 (the total weight of nanocarbon, nanotitania and nanosilica is in accordance with example 3).
Comparative example 3
The only difference from example 3 is that the weight ratio of nanoparticles to pullulan was 5:6 (the total weight of nanoparticles and pullulan was identical to example 3).
Comparative example 4
The only difference from example 3 is that the weight ratio of inorganic mineral powder, chitosan and tea saponin is 0.8:0.9:0.4 (the total weight of inorganic mineral powder, chitosan and tea saponin is the same as in example 3).
Comparative example 5
The difference from the example 3 is only that in the preparation method, the raw materials are directly added into a reaction kettle to be mixed, and the mixture is firstly heated to 58 ℃ and stirred for 30min, and then heated to 82 ℃ and stirred for 30 min.
Comparative example 6
The only difference from example 3 is that without chitosan and chitosan oligosaccharide, the preparation method also deletes the addition of these two components accordingly.
First, capacity repair test
Lead-acid storage batteries (with standard capacity of 500HA) which are realized by sulfate crystallization after 110 batteries are used for 3 years are randomly divided into 11 groups, 10 batteries are arranged in each group, the repairing agents prepared in examples 1-5 and comparative examples 1-6 (the repairing agent is added according to 10% AH of the battery capacity) are respectively added into the grouped storage batteries, the grouped storage batteries are discharged at a rate of 10 hours, the capacity of the repaired batteries is examined after the batteries are circularly charged and discharged for 2 weeks, the capacity repairing rate is calculated, and the test results are counted in a table 1.
TABLE 1
| Examples of the invention | Post-repair capacity (AH) | Capacity repair Rate (%) |
| Example 1 | 475 | 95 |
| Example 2 | 480 | 96 |
| Example 3 | 500 | 100 |
| Example 4 | 500 | 100 |
| Example 5 | 495 | 99 |
| Comparative example 1 | 280 | 56 |
| Comparative example 2 | 320 | 64 |
| Comparative example 3 | 350 | 70 |
| Comparative example 4 | 430 | 86 |
| Comparative example 5 | 420 | 84 |
| Comparative example 6 | 300 | 60 |
As can be seen from Table 1, the repairing agent of each example of the invention can effectively repair the scrapped storage battery, the repairing rate can reach 95-100%, the repairing agent of comparative examples 1-6 has a relatively weaker repairing capability than that of example 3, wherein the capacity repairing rate of comparative example 1 only reaches 56%, and the content change among the components of the repairing agent greatly affects the repairing function of the red repairing agent of the invention. Comparative examples 2-4 are also relatively lower than example 3, and it can be seen that the presence of two or more components in the repair agent stock will also result in some alteration in the repair ability of the repair agent. While comparative example 5 shows the effect of the difference in preparation method on the repair ability of the repair agent. In the comparative example 6, two key components are lacked, the repairing capability of the finally prepared repairing agent is obviously reduced, and the change of the components of the repairing agent can break the material balance of the repairing agent and finally reflect the reduction of the final repairing effect.
Second, cycle life test
110 scrapped storage batteries (standard capacity of 500HA) are selected and randomly divided into 11 groups, 10 sections of each group are added, the repairing agents prepared in examples 1-5 and comparative examples 1-6 are respectively added (the adding of the repairing agents is added according to 10% AH of the battery capacity), the batteries are continuously discharged for 2h at a stable current of 10A, continuously charged for 4h at a stable voltage of 15V and subjected to multiple cycles at the temperature of 25 ℃, the test is finished when the open-circuit voltage of the storage batteries is lower than 10V, and the cycle times are counted to be in a table 2.
TABLE 2
| Examples of the invention | Number of cycles (times) |
| Example 1 | 1732 |
| Example 2 | 1780 |
| Example 3 | 1864 |
| Example 4 | 1805 |
| Example 5 | 1817 |
| Comparative example 1 | 958 |
| Comparative example 2 | 1150 |
| Comparative example 3 | 1224 |
| Comparative example 4 | 1318 |
| Comparative example 5 | 1285 |
| Comparative example 6 | 997 |
As shown in Table 2, the number of cycles of the repairing agent in examples 1-5 of the present invention under certain conditions can reach 1732-1864, wherein the maximum number of cycles of example 3 can reach 1864. The cycle times of the batteries repaired by the repairing agents in comparative examples 1-6 are all inferior to that of example 3, and it can be seen that the influence of the components and contents of the adsorbent greatly influences the service life of the repairing agent, and the repairing agent prepared by the composition and the proportion of the repairing agent in the protection range of the application and the corresponding preparation method can have a longer service life.
Finally, it should be noted that the above-mentioned contents are only used for illustrating the technical solutions of the present invention, and not for limiting the protection scope of the present invention, and that the simple modifications or equivalent substitutions of the technical solutions of the present invention by those of ordinary skill in the art can be made without departing from the spirit and scope of the technical solutions of the present invention.
