Description

Technical Field

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

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

[0003] Sulfation means that PbSO4 (lead sulfate) on the negative electrode irreversibly changes into PbO2 (lead dioxide) and Pb (lead). Sulfation is inevitable. The sulfation of the electrode plate is generally caused by phenomena such as long-term undercharging, negative electrode depolarization, failure to charge in time after discharge, too high electrolyte concentration, and electrolyte stratification. As more and more sulfates accumulate on the electrode plate, the 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, deteriorating the starting performance of the composite lead-carbon battery, and even causing the battery to fail severely in serious cases.

[0045] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

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

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

[0048] Among them, bolts 9 are respectively rotatably connected to the four corners of the protection cover 8, threaded holes 701 matching the bolts 9 are formed in the protection frame 7, and the bolts 9 and the threaded holes 701 can be threadedly connected. That is, the protection frame 7 and the protection cover 8 are fixed by the cooperation of the protection frame 7 and the threaded holes 701. The protection frame 7 and the protection cover 8 cooperate to completely wrap the composite lead-carbon battery, and both the protection frame 7 and the protection cover 8 can be made of elastic materials such as rubber, polyurethane, silica gel, etc., so that when the composite lead-carbon battery is impacted, it plays a certain buffering role.

[0049] As Figures 1 to 8 shown, an exhaust port 5 is provided on the battery cover 2, and a gas filtering structure 11 matching the exhaust port 5 is installed on the protection cover 8. The water vapor and hydrogen generated during the use of the composite lead-carbon battery will enter the gas filtering structure 11, and the gas filtering structure 11 separates hydrogen from other gases.

[0050] Specifically, as Figures 12 to 13As shown in the figure, the air filtration structure 11 includes a first tank body 12. A first intake pipe 13 is installed between the first tank body 12 and the battery housing 1. That is, one end of the first intake pipe 13 away from the first tank body 12 is connected to the exhaust port 5, enabling the water vapor and hydrogen generated by the composite lead-carbon battery to enter the first tank body 12 through the first intake pipe 13. A metal palladium cylinder 14 is installed inside the first tank body 12. The metal palladium cylinder 14 can absorb hydrogen. The principle is that hydrogen reacts chemically with palladium 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, during the process of the metal palladium cylinder 14 absorbing hydrogen, it is an endothermic reaction, that is, heat is absorbed during the reaction process. This can reduce the temperature of other gases inside the first tank body 12, that is, it can absorb the heat of the water vapor, reduce the temperature of the water vapor, and accelerate the speed of the water vapor condensing into water.

[0052] As Figures 12 to 13 shown in the figure, a plurality of through holes 1401 for hydrogen to pass through are provided on the metal palladium cylinder 14. By setting a plurality of through holes 1401, the contact surface between hydrogen and the metal palladium cylinder 14 is increased, enabling the metal palladium cylinder 14 to adsorb more hydrogen. A hollow cavity 1402 is also provided on the metal palladium cylinder 14. A plurality of heating tubes 15 are fixedly connected inside the hollow cavity 1402. The heating tubes 15 can heat the metal palladium cylinder 14, and heating the metal palladium cylinder 14 causes the metal palladium cylinder 14 to release hydrogen. That is, before releasing hydrogen, the gas inside the first tank body 12 is evacuated and the first tank body 12 is made in a closed state. Then, the metal palladium cylinder 14 is heated through the heating tubes 15. After the metal palladium cylinder 14 releases hydrogen, there will be a large amount of hydrogen inside the first tank body 12.

[0053] As Figures 1 to 8 shown in the figure, a cooling structure 16 is fixedly connected to the protective cover 8. The cooling structure 16 is in communication with the air filtration structure 11, and the gas inside the air filtration structure 11 can enter the cooling structure 16, while the gas inside the cooling structure 16 cannot enter the air filtration structure 11. The cooling structure 16 can store the gas passing through the air filtration structure 11 and cool it inside the cooling structure 16. The gas entering the cooling structure 16 through the air filtration structure 11 is generally water vapor. The water vapor will condense into water in the cooling structure 16, and the water will then enter the air filtration structure 11 to realize the circulation of water, avoiding the loss of moisture in the electrolyte, avoiding the situation where the battery performance decreases due to the loss of moisture in the electrolyte, and also reducing the risk of battery thermal runaway, which is beneficial to extending the service life of the composite lead-carbon battery.

[0054] As 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. A first liquid adding 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 condenses into water, it flows into the interior of the composite lead-carbon battery through the first liquid adding pipe 20 to supplement the water in the electrolyte of the composite lead-carbon battery.

[0055] As Figures 1 to 8 shown, a number of air bags 19 are also installed on the first connecting pipe 18. If the temperature of the composite lead-carbon battery is too high and too much water vapor is generated by the composite lead-carbon battery, and the second tank body 17 cannot effectively store and cool the water vapor, at this time, 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 extremely prone to thermal runaway. By providing the air bags 19 on the first connecting pipe 18, in a high-pressure state, the air bags 19 can deform to expand the space of the composite lead-carbon battery, enabling the composite lead-carbon battery to store more water vapor and preventing the composite lead-carbon battery from being in a high-pressure state. Greatly improving the safety of the composite lead-carbon battery.

[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. The water vapor is cooled and condensed into water, and then flows back to the composite lead-carbon battery for utilization. Without affecting the normal heat dissipation of the composite lead-carbon battery, the consumption rate of the electrolyte of the composite lead-carbon battery is reduced, which is beneficial to extending the service life of the composite lead-carbon battery.

[0057] It was mentioned above that the metal palladium cylinder 14 in the gas filtering structure 11 is used to absorb hydrogen, and the hydrogen absorbed by the metal palladium cylinder 14 can be released by heating. As Figures 1 to 11 shown, an energy supply structure 21, an energy conversion structure 27 and an energy storage structure 42 are installed on the protective cover 8. The energy supply structure 21 can transport the hydrogen released by the metal palladium cylinder 14 in the gas filtering structure 11 to the energy conversion structure 27. The energy conversion structure 27 can cause the hydrogen to explode, and the energy generated by the explosion is converted into electric energy by the energy storage structure 42 and can be used on the positive electrode plate 3 and the negative electrode plate 4 of the composite lead-carbon battery. The positive electrode plate 3 and the negative electrode plate 4 are impacted in a high-frequency and high-current manner, so that the sulfates on the positive electrode plate 3 and the negative electrode plate 4 fall off, avoiding the situation where sulfate crystals occupy the active material space of the electrode plate and hinder the contact between the electrolyte and the electrode plate, which is beneficial to improving the charge and discharge efficiency of the composite lead-carbon battery and beneficial to improving the starting performance of the composite lead-carbon battery.

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

[0059] Before heating to release the hydrogen in the metal palladium cylinder 14, to improve the purity of hydrogen, it is necessary to drain other gases in the first tank 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 12 will enter the first connecting pipe 18 through the second intake 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 12 is in a relatively vacuum state, and then the heating pipe 15 is used to heat the metal palladium cylinder 14 to release hydrogen.

[0060] As Figures 1 to 11 As shown, the energy conversion structure 27 includes a first housing 28. A partition 30 is slidably connected in the first housing 28. An outer wall of the partition 30 is fixedly connected with a sealing ring 33 that matches the inner wall of the first housing 28. The partition 30 can divide the space in the first housing 28 into a first chamber 31 and a second chamber 32. A fourth intake pipe 29 is provided on the first housing 28. One end of the first exhaust pipe 25 away from the pump 22 is communicated with the fourth intake pipe 29. The fourth intake pipe 29 is communicated with the first chamber 31. When hydrogen enters the first chamber 31, it will drive the partition 30 to move towards the end away from the first chamber 31. The kinetic energy generated by the movement is converted into electric energy by the power generation structure 36. When the amount of hydrogen in the first chamber 31 reaches a certain level, the supply of hydrogen to the first chamber 31 will stop. And a certain amount of air is supplied to 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 rapidly towards 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 way of generating electricity by the cooperation of the energy conversion structure 27 and the power generation structure 36 is still other power generation methods. For example, it is realized by using a hydrogen fuel cell to directly convert the chemical energy of hydrogen and oxygen into electric energy, combustion power generation, etc.

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

[0062] As Figures 1 to 11 shown, the power generation structure 36 includes a rack 39. A slideway 2801 matching the rack 39 is provided on the first housing 28, and the rack 39 is slidably connected within the slideway 2801. A motor 37 matching the rack 39 is installed on the outer wall of the first housing 28. 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, it can drive the gear 38 to rotate, thereby driving the motor 37 to generate electricity.

[0063] Specifically, as Figures 1 to 11 shown, a first magnet block 34 is fixedly connected inside the sealing ring 33, and a third magnet block 40 matching the first magnet block 34 is fixedly connected to the rack 39. The first magnet block 34 and the third magnet block 40 adsorb each other. That is, during the movement of the partition 30, the rack 39 can be driven to move.

[0064] As Figures 1 to 11 shown, a second magnet block 35 is fixedly connected to the bottom wall of the first chamber 31. The first magnet block 34 and the second magnet block 35 also adsorb 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. During the process of conveying hydrogen into the first chamber 31, the sealing ring 33 gradually moves away from the second magnet block 35, and at the same time drives the rack 39 to slide upward, and the rack 39 drives the motor 37 to generate electricity.

[0065] Among them, as Figure 10 shown, an exhaust valve 53 is also installed on the side wall of the first chamber 31. After a micro-explosion occurs in the first chamber 31, water will be generated, and its reaction equation is: 2H2 + O2 == 2H2O. When the pressure generated by the explosion is too high, the pressure will be discharged from the exhaust valve 53 to avoid damage to the composite lead-carbon battery and the first housing 28 caused by excessive pressure. The water generated by the explosion of hydrogen and oxygen is stored in the first chamber 31.

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

[0067] In addition, the electricity stored in the energy storage structure 42 can not only be supplied to the positive plate 3 and the negative plate 4, but also charge the composite lead-carbon battery after deep discharge to ensure that the battery is charged in time after discharge, so as to avoid the 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 the energy storage structure 42 stores a certain amount of electricity, it can be directly used as a backup power supply. 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, which can avoid over-discharge of the composite lead-carbon battery, thereby improving the service life of the composite lead-carbon battery.

[0069] As Figures 1 to 11 shown, the energy storage structure 42 includes a micro battery 43. A power interface (not shown in the figure) is provided on the micro battery 43, and power can be supplied to the outside through the power interface. 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 electrical energy is stored in the first power line 41 through the first power line 41. A second power line 44 is installed on the micro battery 43, and one 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 judges whether to supply pulsed power to the positive plate 3 or the negative plate 4 with multiple frequencies and large current 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] As Figures 1 to 11 shown, the detection structure 50 includes a voltage detector 51. A third power line 52 matching the positive plate 3 and the negative plate 4 is installed on the voltage detector 51. Through the third power line 52, the positive plate 3 or the negative plate 4 can be electrically connected, 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 power storage effect of the composite lead-carbon battery is worse. Therefore, a voltage threshold can be set. When the voltage drops to a certain value, the energy storage structure 42 supplies electrical energy to the positive plate 3 and the negative plate 4 to achieve the removal of sulfate.

[0071] Specifically, there are generally two ways for the voltage threshold. One is the threshold for the high lifespan of the composite lead-carbon battery, and the other is the threshold for the high output and high storage of the composite lead-carbon battery. 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 for 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 sulfate on the positive plate 3 and the negative plate 4 of the composite lead-carbon battery can be removed, enabling the composite lead-carbon battery to maintain a state of high output and high storage. Specifically, the voltage of the composite lead-carbon battery can be selected according to the actual usage situation.

[0072] As Figures 1 to 11 shown, a water storage structure 45 is installed on the protective cover 8. The water storage structure 45 can store the water generated by the energy conversion structure 27. When the composite lead-carbon battery needs to be refilled with water, the water in the water storage structure 45 can be used to add water into the battery housing 1 to avoid the situation of too low moisture content in the electrolyte. 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 supply water to the composite lead-carbon battery for heat dissipation.

[0073] Specifically, as Figures 1 to 11 shown, the water storage structure 45 includes a water storage tank 46. A first water pipe 47 is installed between the water storage tank 46 and the first housing 28. The water generated by the hydrogen reaction is stored in the first housing 28 and is transported to the water storage tank 46 through the first water pipe 47. A second water pipe 48 matching the first liquid adding pipe 20 is installed on the water storage tank 46. The second water pipe 48 can transport water into the first liquid adding pipe 20, and then the first liquid adding pipe 20 transports the water into the battery housing 1 to complete the water replenishment operation of the composite lead-carbon battery.

[0074] As Figures 1 to 11 shown, a drain port 49 is provided on the water storage tank 46. A heat dissipation pipe 10 matching the drain port 49 is fixedly connected to the protective frame 7. The heat dissipation pipe 10 has a liquid outlet end 1001 and a liquid inlet end 1002, and the liquid outlet end 1001 is communicated with the drain port 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 end 1002. It can achieve the rapid cooling of the composite lead-carbon battery in the extreme high-temperature state of the composite lead-carbon battery.

[0075] As Figures 1 to 5As shown, a pre-installation part 801 is further provided on the protective cover 8. A plurality of detection devices are installed on the pre-installation part 801, and the detection devices can be arbitrarily installed on the protective cover 8 to detect the state of the composite lead-carbon battery. Specifically, the pre-installation part 801 includes a number of pre-installation holes 8011 with different specifications. Different detection devices can be installed on the pre-installation holes 8011 through the pre-installation holes 8011.

[0076] During assembly, first, the positive electrode plate 3 and the negative electrode 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 through 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. The voltage of the composite lead-carbon battery is detected through the detection structure 50. The water storage structure 45 is connected to the heat dissipation pipe 10 and is connected to the first liquid adding pipe 20.

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

[0078] After the hydrogen in the metal palladium cylinder 14 is saturated with adsorption, the heating pipe 15 heats the metal palladium cylinder 14, and the hydrogen in the metal palladium cylinder 14 is released and stored in the first tank 12. The hydrogen in the first tank 12 is pumped into the energy conversion structure 27 by the energy supply structure 21, and air is pumped into the energy conversion structure 27 by the energy supply structure 21 to realize the mixing of hydrogen and air. Then the mixed gas of air and hydrogen is ignited by the igniter 54 to cause the hydrogen to explode. The energy generated during the explosion process is converted into electric 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 for waiting to be used. The water generated during the explosion process of the energy conversion structure 27 can be discharged into 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 supplied to the positive electrode plate 3 and the negative electrode plate 4 to separate the sulfate from the positive electrode plate 3 and the negative electrode plate 4, so as to obtain a battery with a larger capacity, which is beneficial to improving the service life of the composite lead-carbon battery. Or the composite lead-carbon battery can always maintain a large-capacity state.
