Description

Technical Field

[0001] The invention belongs to the technical field of batteries, and in particular relates to a composite lead-carbon battery and a preparation method thereof. Background Art

[0002] Composite lead-carbon batteries are obtained by adding carbon materials to the negative electrode of traditional lead-acid batteries. The addition of carbon materials accelerates the conversion of active substances during the conversion process, and new active centers are formed on the surface of activated carbon, which reduces the polarization during the plate charging process and inhibits the growth of lead sulfate particles, which is beneficial to the reduction of lead sulfate. Therefore, adding an appropriate amount of carbon to lead-acid batteries can effectively inhibit the accumulation of lead sulfate crystals on the negative electrode surface, slow down the trend of sulfation, and significantly increase the battery cycle life.

[0003] Sulfation is the PbSO on the negative electrode 4 (Lead sulfate) irreversibly converts to PbO 2 (Lead dioxide) and Pb (lead), sulfation is inevitable. Plate sulfation is generally caused by long-term undercharging, negative electrode depolarization, failure to charge in time after discharge, too high electrolyte concentration, electrolyte stratification, etc. As more and more sulfate accumulates on the plate, sulfate crystals will occupy the active material space of the electrode plate, hindering the contact between the electrolyte and the electrode plate, thereby affecting the charge and discharge efficiency of the composite lead-carbon battery, making the starting performance of the composite lead-carbon battery worse, and even causing battery failure in severe cases.

DETAILED DESCRIPTION

[0045] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0046] like Figures 1 to 8 As shown, a composite lead-carbon battery in one embodiment of the present invention includes a battery housing 1, in which a positive plate 3 and a negative plate 4 are installed, and the battery housing 1 is filled with an electrolyte. A battery cover 2 is fixedly connected to the upper end of the battery housing 1, and a portion of the positive plate 3 and the negative plate 4 are fixedly connected to the battery cover 2 and are located outside the battery cover 2.

[0047] like Figures 1 to 8 As shown, the composite lead-carbon battery also includes a protective structure 6, which can protect the composite lead-carbon battery to a certain extent and reduce the damage caused by the composite lead-carbon battery when it is hit. Specifically, the protective structure 6 includes a protective frame 7, and the composite lead-carbon battery can be placed inside the protective frame 7. The upper end of the protective frame 7 is fixedly connected with a protective cover 8. The protective frame 7 and the protective cover 8 cooperate to form protection on the outside of the composite lead-carbon battery to protect the composite lead-carbon battery.

[0048] Among them, bolts 9 are rotatably connected at the four corners of the protective cover 8, and threaded holes 701 matching the bolts 9 are provided on the protective frame 7, and the bolts 9 and the threaded holes 701 can be threadedly connected. That is, the protective frame 7 and the protective cover 8 are fixed by the protective frame 7 and the threaded holes 701. The protective frame 7 and the protective cover 8 can completely wrap the composite lead-carbon battery, and the protective frame 7 and the protective cover 8 can be made of elastic materials, such as rubber, polyurethane, silicone, etc., so that the composite lead-carbon battery can play a certain buffering role when it is hit.

[0049] like Figures 1 to 8 As shown, the battery cover 2 is provided with an exhaust port 5, and the protective cover 8 is installed with an air filter structure 11 matching the exhaust port 5. The water vapor and hydrogen generated by the composite lead-carbon battery during use will enter the air filter structure 11, and the air filter structure 11 will separate the hydrogen and other gases.

[0050] Specifically, Figure 12-13As shown, the air filter structure 11 includes a first tank body 12, and a first air inlet pipe 13 is installed between the first tank body 12 and the battery housing 1, that is, the end of the first air inlet pipe 13 away from the first tank body 12 is connected to the exhaust port 5, so that the water vapor and hydrogen generated by the composite lead-carbon battery can enter the first tank body 12 through the first air inlet pipe 13. A metal palladium cylinder 14 is installed in the first tank body 12, and the metal palladium cylinder 14 can absorb hydrogen. The principle is that hydrogen and palladium react chemically to form a compound of the metal palladium cylinder 14 and hydrogen. At room temperature, the metal palladium cylinder 14 can absorb a large amount of hydrogen to form palladium hydride. Palladium hydride is a very stable compound and can store and release hydrogen. The reaction formula for the metal palladium cylinder 14 to absorb hydrogen is Pd+H2→PdH2.

[0051] Moreover, the metal palladium cylinder 14 absorbs heat in the process of absorbing hydrogen, which is an endothermic reaction. That is, it absorbs heat during the reaction, which can reduce the temperature of other gases in the first tank body 12, that is, it can absorb the heat of water vapor, reduce the temperature of water vapor, and accelerate the condensation rate of water vapor into water.

[0052] like Figure 12-13 As shown, the metal palladium cylinder 14 is provided with a plurality of through holes 1401 for hydrogen to pass through. By providing a plurality of through holes 1401, the contact surface between hydrogen and the metal palladium cylinder 14 is increased, so that the metal palladium cylinder 14 can absorb more hydrogen. The metal palladium cylinder 14 is also provided with a hollow cavity 1402, and a plurality of heating tubes 15 are fixedly connected to the inside of the hollow cavity 1402. The heating tube 15 can heat the metal palladium cylinder 14, and the metal palladium cylinder 14 is heated to release hydrogen. That is, before releasing hydrogen, the gas in the first tank body 12 is evacuated, and the first tank body 12 is in a closed state, and then the metal palladium cylinder 14 is heated by the heating tube 15. After the metal palladium cylinder 14 releases hydrogen, a large amount of hydrogen will be present in the first tank body 12.

[0053] like Figures 1 to 8 As shown, a cooling structure 16 is fixedly connected to the protective cover 8, and the cooling structure 16 is connected to the air filter structure 11, and the gas in the air filter structure 11 can enter the cooling structure 16, while the gas in the cooling structure 16 cannot enter the air filter structure 11. The cooling structure 16 can store the gas that has passed through the air filter structure 11 and cool it in the cooling structure 16. The gas that passes through the air filter structure 11 and enters the cooling structure 16 is generally water vapor, which condenses into water in the cooling structure 16, and the water then enters the air filter structure 11, realizing the circulation of water, avoiding the loss of water in the electrolyte, avoiding the situation where the battery performance is reduced due to the loss of water in the electrolyte, and reducing the risk of thermal runaway of the battery, which is conducive to extending the service life of the composite lead-carbon battery.

[0054] like Figures 1 to 8As shown, the cooling structure 16 includes a second tank body 17, a first connecting pipe 18 is installed between the second tank body 17 and the first tank body 12, and a first liquid filling pipe 20 matching the composite lead-carbon battery is fixedly connected to the second tank body 17. After the water vapor in the second tank body 17 is condensed into water, it flows into the interior of the composite lead-carbon battery through the first liquid filling pipe 20 to replenish the water in the electrolyte of the composite lead-carbon battery.

[0055] like Figures 1 to 8 As shown, several airbags 19 are also installed on the first connecting tube 18. If the temperature of the composite lead-carbon battery is too high, the composite lead-carbon battery generates too much water vapor, and the second tank body 17 cannot effectively store and cool the water vapor, then the water vapor inside the composite lead-carbon battery cannot be discharged and will be in a high-pressure state. In this state, the composite lead-carbon battery is very likely to have thermal runaway. By arranging the airbag 19 on the first connecting tube 18, the airbag 19 can be deformed under high-pressure conditions to expand the space of the composite lead-carbon battery, so that the composite lead-carbon battery can store more water vapor and avoid the composite lead-carbon battery being in a high-pressure state. The safety of the composite lead-carbon battery is greatly improved.

[0056] By filtering the water vapor and hydrogen generated by the composite lead-carbon battery through the gas filtering structure 11, the gas entering the cooling structure 16 is only water vapor, which is cooled and condensed into water and then flows back to the composite lead-carbon battery for utilization. This does not affect the normal heat dissipation of the composite lead-carbon battery, while reducing the consumption rate of the electrolyte of the composite lead-carbon battery, which is beneficial to extending the service life of the composite lead-carbon battery.

[0057] It is mentioned above that the metal palladium cylinder 14 in the air filter structure 11 is used to absorb hydrogen, and the hydrogen absorbed by the metal palladium cylinder 14 can be released by heating. Figures 1 to 11 As shown, the protective cover 8 is equipped with an energy supply structure 21, an energy conversion structure 27 and an energy storage structure 42. The energy supply structure 21 can transport the hydrogen released by the metal palladium cylinder 14 in the air filter structure 11 to the energy conversion structure 27. The energy conversion structure 27 can cause the hydrogen to explode. The energy generated by the explosion is converted into electrical energy by the energy storage structure 42, and the electrical energy can be used on the positive plate 3 and the negative plate 4 of the composite lead-carbon battery. The positive plate 3 and the negative plate 4 are impacted in a high-frequency and high-current manner to cause the sulfate on the positive plate 3 and the negative plate 4 to fall off, thereby avoiding the situation where sulfate crystallization occupies the active material space of the electrode plate and hinders the contact between the electrolyte and the electrode plate, which is beneficial to improving the charging and discharging efficiency of the composite lead-carbon battery and improving the starting performance of the composite lead-carbon battery.

[0058] like Figures 1 to 11As shown, the energy supply structure 21 includes a pump 22, and a second air inlet pipe 23 is installed at the input end of the pump 22, and the end of the second air inlet pipe 23 away from the pump 22 is connected to the first tank body 12. A first exhaust pipe 25 is installed at the output end of the pump 22, and the end of the first exhaust pipe 25 away from the pump 22 is connected to the energy conversion structure 27. That is, through the cooperation of the pump 22, the second air inlet pipe 23 and the first exhaust pipe 25, the gas in the first tank body 12 can be transported to the energy conversion structure 27, waiting for the energy conversion structure 27 to convert hydrogen into electrical energy.

[0059] Before heating and releasing the hydrogen in the metal palladium cylinder 14, in order to improve the purity of the hydrogen, it is necessary to discharge other gases in the first tank body 12 through the energy supply structure 21. A second exhaust pipe 26 is installed between the first exhaust pipe 25 and the first connecting pipe 18. Before transporting hydrogen, the gas in the first tank body 12 will enter the first connecting pipe 18 through the second air inlet pipe 23, the pump 22 and the second exhaust pipe 26, and the gas in the first connecting pipe 18 will enter the cooling structure 16 for cooling. At this time, the first tank body 12 is in a relatively vacuum state, and the heating tube 15 is used to heat the metal palladium cylinder 14 to release hydrogen.

[0060] like Figures 1 to 11 As shown, the energy conversion structure 27 includes a first shell 28, a partition 30 is slidably connected in the first shell 28, and a sealing ring 33 matching the inner wall of the first shell 28 is fixedly connected to the outer wall of the partition 30. The partition 30 can divide the space in the first shell 28 into a first chamber 31 and a second chamber 32. A fourth air inlet pipe 29 is provided on the first shell 28, and the end of the first exhaust pipe 25 away from the pump 22 is connected to the fourth air inlet pipe 29. The fourth air inlet pipe 29 is connected to the first chamber 31. When hydrogen enters the first chamber 31, it will move with the partition 30 to the end away from the first chamber 31, and the kinetic energy generated by the movement will be converted into electrical energy by the power generation structure 36. When the amount of hydrogen in the first chamber 31 reaches a certain level, the hydrogen will be stopped from being transported into the first chamber 31. A certain amount of air is transported into the first chamber 31 to combine hydrogen with oxygen in the air. An igniter 54 is installed in the first chamber 31. The igniter 54 ignites the mixed gas in the first chamber 31, which will cause an explosion. The energy generated by the explosion will push the partition 30 to move quickly to the end away from the first chamber 31, and cooperate with the power generation structure 36 to achieve high-power power generation. Of course, the energy conversion structure 27 and the power generation structure 36 cooperate to generate electricity in other ways, such as by using a hydrogen fuel cell to directly convert the chemical energy of hydrogen and oxygen into electrical energy, combustion power generation, etc.

[0061] Among them, a third air intake pipe 24 is installed on the second air intake pipe 23. When air is pumped, the third air intake pipe 24, the second air intake pipe 23, the pump 22 and the first exhaust pipe 25 form an air passage, and the air enters the second exhaust pipe 26 through the air passage and mixes with the hydrogen in the second exhaust pipe 26.

[0062] like Figures 1 to 11 As shown, the power generation structure 36 includes a rack 39, and a slideway 2801 matching the rack 39 is provided on the first housing 28, and the rack 39 is slidably connected in the slideway 2801. A motor 37 matching the rack 39 is mounted on the outer wall of the first housing 28, and a gear 38 matching the rack 39 is fixedly connected to the output shaft of the motor 37. During the sliding process of the rack 39, the gear 38 can be rotated with it, thereby driving the motor 37 to generate electricity.

[0063] Specifically, Figures 1 to 11 As shown, the sealing ring 33 is fixedly connected to the inside with a first magnet block 34, and the rack 39 is fixedly connected to a third magnet block 40 matching the first magnet block 34, and the first magnet block 34 and the third magnet block 40 are mutually attracted. That is, when the partition 30 moves, it can move with the rack 39.

[0064] like Figures 1 to 11 As shown, the bottom wall of the first chamber 31 is fixedly connected with the second magnet block 35, and the first magnet block 34 and the second magnet block 35 are also attracted to each other. When there is no hydrogen in the first chamber 31, the outer wall of the sealing ring 33 is in contact with the second magnet block 35. In the process of transporting hydrogen into the first chamber 31, the sealing ring 33 gradually moves away from the second magnet block 35, and at the same time slides upward with the rack 39, and the rack 39 drives the motor 37 to generate electricity.

[0065] Among them, Fig.10 As shown, an exhaust valve 53 is also installed on the side wall of the first chamber 31. When a micro-explosion occurs in the first chamber 31, water will be produced, and the reaction equation is: 2H2+O2==2H2O. When the pressure generated by the explosion is too large, the pressure will be discharged from the exhaust valve 53 to avoid the situation where the composite lead-carbon battery and the first shell 28 are damaged by excessive pressure. The water produced by the explosion of hydrogen and oxygen is stored in the first chamber 31.

[0066] like Figures 1 to 11 As shown, an energy storage structure 42 is installed on the protective cover 8, and the electricity generated by the power generation structure 36 is stored by the energy storage structure 42 and can be provided to the electronic components on the protective cover 8 for use. Generally, the electricity in the energy storage structure 42 is used for the positive plate 3 and the negative plate 4. The energy storage structure 42 provides electricity to the positive plate 3 and the negative plate 4 in a multi-frequency and high-current manner, so that the sulfate attached to the positive plate 3 and the negative plate 4 falls off.

[0067] In addition, in addition to being provided to the positive plate 3 and the negative plate 4, the electricity stored in the energy storage structure 42 can also charge the composite lead-carbon battery after deep discharge to ensure that the battery is charged in time after discharge to avoid sulfation of the positive plate 3 and the negative plate 4.

[0068] However, during the initial use of the composite lead-carbon battery, desulfation is not required. Therefore, after storing a certain amount of electricity, the energy storage structure 42 can be directly used as a backup power source. When the power supply of the composite lead-carbon battery is insufficient, the composite lead-carbon battery stops providing electrical energy, and the electrical energy is provided by the energy storage structure 42. This can avoid excessive discharge of the composite lead-carbon battery, thereby increasing the service life of the composite lead-carbon battery.

[0069] like Figures 1 to 11 As shown, the energy storage structure 42 includes a micro battery 43, and a power interface is provided on the micro battery 43, which is not shown in the figure. The power interface can provide power to the outside. A first power line 41 is installed between the micro battery 43 and the power generation structure 36. After the energy conversion structure 27 and the power generation structure 36 cooperate to generate electricity, the electric energy is stored in the first power line 41 by the first power line 41. A second power line 44 is installed on the micro battery 43, and the end of the second power line 44 away from the micro battery 43 is respectively connected to the positive plate 3 and the negative plate 4. A detection structure 50 is installed on the protective cover 8. The micro battery 43 determines whether it is necessary to provide multi-frequency and large current pulse power supply to the positive plate 3 or the negative plate 4 according to the detection result of the detection structure 50, so as to remove the sulfate on the positive plate 3 or the negative plate 4.

[0070] like Figures 1 to 11 As shown, the detection structure 50 includes a voltage detector 51, and a third power line 52 matching the positive plate 3 and the negative plate 4 is installed on the voltage detector 51. The positive plate 3 or the negative plate 4 can be electrically connected through the third power line 52, so that the voltage detector 51 can always detect the voltage of the composite lead-carbon battery. That is, the battery capacity of the composite lead-carbon battery is related to the voltage of the battery. When the voltage is lower, the effect of storing electricity of the composite lead-carbon battery is worse. Therefore, a voltage threshold can be set. When the voltage is lower than a certain value, the energy storage structure 42 provides electrical energy to the positive plate 3 and the negative plate 4 to achieve the removal of sulfate.

[0071] Specifically, the voltage threshold can generally be set in two ways, one is the threshold that makes the composite lead-carbon battery have a long life, and the other is the threshold that makes the composite lead-carbon battery have high output and high storage. That is, in order to extend the service life of the composite lead-carbon battery, the voltage threshold can be set lower so that the composite lead-carbon battery can be used for a long time. In order to enable the composite lead-carbon battery to have high output and high storage, when the voltage threshold of the composite lead-carbon battery reaches a certain level, the positive plate 3 and the negative plate 4 on the composite lead-carbon battery can be removed from sulfate, so that the composite lead-carbon battery maintains a high output and high storage state. The specific voltage of the composite lead-carbon battery can be selected according to actual usage.

[0072] like Figures 1 to 11 As shown, a water storage structure 45 is installed on the protective cover 8, and the water storage structure 45 can store the water generated by the energy conversion structure 27. When the composite lead-carbon battery needs to add water, the water in the water storage structure 45 can be used to add water to the battery housing 1 to avoid the situation where the water content of the electrolyte is too low. During the use of the composite lead-carbon battery, hydrogen is continuously generated, and the energy conversion structure 27 can continuously generate water. The water is collected in the water storage structure 45. When the battery needs to dissipate heat quickly, the water storage structure 45 can provide water to the composite lead-carbon battery for heat dissipation.

[0073] Specifically, Figures 1 to 11 As shown, the water storage structure 45 includes a water storage tank 46, and a first water delivery pipe 47 is installed between the water storage tank 46 and the first shell 28. The water generated by the hydrogen reaction is stored in the first shell 28 and delivered to the water storage tank 46 through the first water delivery pipe 47. A second water delivery pipe 48 matching the first liquid adding pipe 20 is installed on the water storage tank 46. The second water delivery pipe 48 can deliver water to the first liquid adding pipe 20, and then the first liquid adding pipe 20 delivers the water to the battery shell 1, completing the water replenishment operation of the composite lead-carbon battery.

[0074] like Figures 1 to 11 As shown, a water outlet 49 is provided on the water storage tank 46, and a heat dissipation pipe 10 matching the water outlet 49 is fixedly connected to the protection frame 7, and the heat dissipation pipe 10 has a liquid outlet 1001 and a liquid inlet 1002, and the liquid outlet 1001 is connected to the water outlet 49. The water in the water storage tank 46 passes through the heat dissipation pipe 10, exchanges heat with the composite lead-carbon battery, and is discharged from the liquid inlet 1002. The composite lead-carbon battery can be quickly cooled down when the composite lead-carbon battery is in an extremely high temperature state.

[0075] like Figure 1 to Figure 5As shown, the protective cover 8 is also provided with a pre-installation portion 801, on which a plurality of detection devices are installed, and the detection devices can be installed on the protective cover 8 at will to detect the state of the composite lead-carbon battery. Specifically, the pre-installation portion 801 includes a plurality of pre-installation holes 8011 of different specifications, through which different detection devices can be installed on the pre-installation holes 8011.

[0076] During assembly, first, the positive plate 3 and the negative plate 4 are installed in the battery housing 1, and the battery cover 2 is fixedly connected to the upper end of the battery housing 1. Then the battery housing 1 is installed in the protective structure 6, and the protective structure 6, the battery housing 1 and the protective cover 8 are locked by the protective cover 8. Then the air filter structure 11 is connected to the battery housing 1, and then the detection structure 50 is connected to the battery housing 1, and the voltage of the composite lead-carbon battery is detected by the detection structure 50. The water storage structure 45 is connected to the heat dissipation pipe 10 and connected to the first liquid filling pipe 20.

[0077] The hydrogen and water vapor generated during the use of the composite lead-carbon battery enter the first tank body 12 through the first air inlet pipe 13. The metal palladium cylinder 14 in the first tank body 12 can separate the hydrogen and water vapor. The hydrogen is absorbed by the metal palladium cylinder 14. The separated water vapor enters the second tank body 17 and is cooled naturally or by other cooling methods. The water vapor condenses into water, which then enters the battery housing 1 to mix the water and the electrolyte, completing the electrolyte replenishment operation.

[0078] After the hydrogen in the metal palladium cylinder 14 is saturated with adsorption, the heating tube 15 heats the metal palladium cylinder 14, and the hydrogen in the metal palladium cylinder 14 is released and stored in the first tank body 12. The hydrogen in the first tank body 12 is pumped into the energy conversion structure 27 by the energy supply structure 21, and the air is pumped into the energy conversion structure 27 through the energy supply structure 21 to achieve the mixing of hydrogen and air, and then the mixed gas of air and hydrogen is ignited by the igniter 54 to make the hydrogen explode. The energy generated during the explosion is converted into electrical energy by the power generation structure 36, and the electricity generated by the power generation structure 36 is stored in the energy storage structure 42, waiting for use. The water generated during the explosion of the energy conversion structure 27 can be discharged to the water storage structure 45 through the first water pipe 47 for storage.

[0079] The electric energy in the energy storage structure 42 can be provided to the positive plate 3 and the negative plate 4, so that the sulfate is separated from the positive plate 3 and the negative plate 4, thereby obtaining a battery with a larger capacity, which is beneficial to prolonging the service life of the composite lead-carbon battery. Or the composite lead-carbon battery can always maintain a large capacity state.
