Description

Technical Field

[0001] This invention relates to the field of lead-acid battery technology, specifically to a high and low temperature resistant lead-acid battery and its preparation method. Background Technology

[0002] Lead-acid batteries are a type of storage battery made from lead and its oxides, with sulfuric acid solution as the electrolyte. Since their invention, lead-acid batteries have made significant progress in theoretical research, product types and varieties, and electrical performance. In recent years, with the increasing awareness of environmental protection and the development of new energy sources, they have been revitalized. Lead-acid batteries, with their high energy density, long lifespan, and environmental friendliness, have wide applications in the energy storage field, especially in electric vehicles, power storage, and solar energy storage, where market demand is increasing daily. Lead-acid batteries are based on the process of converting chemical energy into electrical energy and consist of plates, separators, and electrolytes. In recent years, the lead-acid battery industry has faced problems such as increasing environmental pressure, overcapacity, and low-price competition. With the increasing global emphasis on environmental protection, governments around the world have introduced relevant policies and regulations to promote the green transformation of the lead-acid battery industry. Due to their low price, readily available materials, and high reliability, lead-acid batteries occupy an important position in chemical battery applications.

[0003] The main defects of lead-acid batteries on the market include short lifespan, easy depletion, large size and weight, environmental pollution, and poor temperature resistance. In low-temperature environments, lead-acid batteries will experience problems such as a slower internal chemical reaction rate, increased electrolyte viscosity, and a reduced reaction rate of active materials on the plates. In high-temperature environments, lead-acid batteries will experience problems such as accelerated electrolyte diffusion, intensified grid corrosion of the plates, and increased internal pressure, which will reduce the lifespan of lead-acid batteries and reduce their performance.

[0004] 1. Patent document CN113193175B discloses a lead-acid battery. The aforementioned patent implements a method of winding conductive wires around a frame body, which supports the conductive wires through the frame body. This greatly reduces the amount of metal used in the conductive wires and the loss of lead raw materials. Furthermore, both the frame body and the supporting ribs are made of acid-resistant materials, which can extend the service life. Multiple conductive coil groups are arranged sequentially and spaced within the frame body, increasing the contact area between the conductive wires and the acid. Therefore, the grid can be made thinner and lighter, improving the utilization rate of active materials. The battery capacity of the same volume can be made higher, or the active material mass of the battery of the same capacity is less, which improves the specific energy of the battery by weight. However, the aforementioned patent cannot achieve the function of protecting lead-acid batteries in high and low temperature environments.

[0005] 2. Patent document CN106575798B discloses a lead-acid battery. The above patent has made efforts to extend the life of the lead-acid battery and can also avoid the defect of electrolyte leakage from the periphery of the negative terminal of the cover at the end of its life. However, the above patent cannot realize the function of monitoring the internal and external environment of the lead-acid battery.

[0006] 3. Patent document CN113871732B discloses an intelligent lead-acid battery. The above patent can prevent the battery from overheating and the electrode plates from softening, which greatly improves the service life of lead-acid batteries. However, the above patent cannot realize the function of monitoring the internal structure and function of lead-acid batteries.

[0007] 4. Patent document CN109244562B discloses a lead-acid battery. This patent achieves a more uniform current density distribution and effectively improves the utilization rate of active materials on the plates by placing the positive and negative busbars on opposite sides of the electrode group, thus extending battery life. In use, the tank opening is placed sideways, and the busbars are horizontal, equivalent to the plates being placed vertically with the shorter side as the height of the electrode group. This reduced electrode group height effectively alleviates acid stratification, reduces concentration polarization, and allows for more uniform utilization of active materials on the plates, extending battery life. However, this patent does not provide protection against accidents involving the lead-acid battery.

[0008] In summary, the aforementioned patents fail to monitor the internal and external environment of lead-acid batteries, fail to monitor the internal structure and function of lead-acid batteries, and fail to provide protection against accidents. This leads to problems such as bulging and deformation of lead-acid batteries in high and low temperature environments, reduced capacity, slower battery response, lack of understanding of the battery's operating environment, reduced battery life and performance, lack of understanding of the quality of internal components affecting performance and reducing user experience, battery leakage, deformation, short circuits, performance degradation, and threats to user safety.

[0009] Therefore, this application proposes a high- and low-temperature resistant lead-acid battery and its preparation method, which can monitor the internal and external environment of the lead-acid battery, monitor the internal structure and function of the lead-acid battery, monitor the internal structure and function of the lead-acid battery, and protect the lead-acid battery in case of accidents.

[0027] The temperature sensor contains a thermistor, a conversion circuit, and a processing unit. Based on the characteristic that the resistance value of the thermistor changes with temperature, when the ambient temperature changes, the resistance value of the thermistor decreases as the temperature rises and rises as the temperature falls. After the conversion circuit and processing unit convert and process the change in the resistance value of the thermistor, the current ambient temperature information is transmitted to the processor.

[0028] Preferably, a quality monitoring module is installed on the upper part of the inner wall of the main body, and the quality monitoring module is connected to the processor through signal transmission;

[0029] The quality monitoring module includes: an acoustic wave detector, a tension sensor, and a sound sensor. The acoustic wave detector is connected to the processor via signal transmission, and the tension sensor is also connected to the processor via signal transmission.

After the external force is removed, the surface charges disappear and return to an uncharged state. The conversion element converts these charges into electrical signals. After the electrical signals are processed by the signal circuit, the acceleration of the vibration is calculated and transmitted to the processor.

[0036] Preferably, the sound sensor is internally equipped with an electret microphone, an amplification circuit, and a processing circuit. When a sound wave acts on the electret microphone, the diaphragm inside the electret microphone moves due to the vibration of the sound wave, causing a change in the capacitance of the electret microphone, which in turn generates a small voltage. After the voltage is processed by the amplification circuit and the processing circuit, the information is transmitted to the processor.

This realizes the function of protecting the lead-acid battery in high and low temperature environments, and solves the problems of bulging and deformation, capacity reduction and reduced battery reaction speed inside the lead-acid battery in high and low temperature environments. It can increase the discharge efficiency of the lead-acid battery, improve the performance of the lead-acid battery, extend the service life of the lead-acid battery, and improve the reliability of the lead-acid battery.

[0083] The humidity sensor 23 is equipped with a humidity-sensitive element, a processing circuit, and an output circuit. Based on the influence of humidity on the conductivity of materials, when the ambient humidity changes, the humidity-sensitive element absorbs hydrogen ions decomposed from water molecules in the air, causing a change in the resistance value of the humidity-sensitive element.

[0086] Example 3

[0087] Please see Figure 1 , Figure 2 and Figure 5 A high and low temperature resistant lead-acid battery, wherein a quality monitoring module 7 is installed on the upper part of the inner wall of the main body 1, and the quality monitoring module 7 is connected to the processor 4 through signal transmission;

[0088] The quality monitoring module 7 includes: an acoustic detector 25, a tension sensor 26, and a sound sensor 27. The acoustic detector 25 is connected to the processor 4 via signal transmission, and the tension sensor 26 is connected to the processor 4 via signal transmission.

[0089] The acoustic wave detector 25 is equipped with an acoustic wave transmitter, a receiver, and a processing circuit. The acoustic wave transmitter emits ultrasonic waves. The higher the concentration of the electrolyte, the faster the ultrasonic waves propagate. The processing circuit records the time when the receiver receives the reflected and transmitted ultrasonic waves. The concentration of the electrolyte is calculated by comparing it with the temperature characteristic parameter curves of different media stored in the pre-stored data, and the information is transmitted to the processor 4.

[0090] The tension sensor 26 contains an elastic body, a resistance strain gauge, and a measuring circuit. Based on the resistance strain effect, when an external force is applied to the tension sensor 26, the elastic body deforms under the force, and the resistance strain gauge attached to the elastic body deforms at the same time. The resistance value of the resistance strain gauge changes.

[0091] The sound sensor 27 is equipped with an electret microphone, an amplification circuit, and a processing circuit. When a sound wave acts on the electret microphone, the diaphragm inside the electret microphone moves due to the vibration of the sound wave, causing a change in the capacitance of the electret microphone, which in turn generates a small voltage. After the voltage is processed by the amplification circuit and the processing circuit, the information is transmitted to the processor 4.

[0092] Furthermore, the acoustic detector 25 emits ultrasonic waves through an acoustic transmitter. The higher the electrolyte concentration, the faster the ultrasonic waves propagate. The processing circuit records the time it takes for the receiver to receive the reflected and transmitted ultrasonic waves. After processing, the information is processed, and the electrolyte concentration is calculated by comparing it with the pre-stored temperature characteristic parameter curves of different media. The information is then transmitted to the processor 4. The tension sensor 26 is based on the resistance strain effect. When an external force is applied to the tension sensor 26, the elastic body deforms under the force, and the resistance strain gauge attached to the elastic body deforms accordingly. The measurement circuit captures, converts, amplifies, and processes the change in resistance value, and then transmits the information to the processor 4.

The processor controls the isolation motor 31 to drive the push rod 32 to push the isolation plate 29 to isolate the inside of the lead-acid battery. The processor 4 also controls the storage tank 30 to open, releasing internal fire extinguishing material to fill the internal space of the lead-acid battery. This provides protection against accidents involving the lead-acid battery, solving problems such as battery leakage, deformation, short circuits, performance degradation, and threats to user safety. It maintains the normal density and level of the electrolyte, extends the battery's lifespan, reduces the likelihood of malfunctions, and improves the safety and reliability of the lead-acid battery.

[0117] The tension sensor 26 contains an elastic body, a resistance strain gauge, and a measuring circuit. Based on the resistance strain effect, when an external force is applied to the tension sensor 26, the elastic body deforms under the force, and the resistance strain gauge attached to the elastic body deforms at the same time. The resistance value of the resistance strain gauge changes. The measuring circuit captures and converts the change in resistance value, and after amplification and processing, converts it into the change value of tension, and transmits the information to the processor 4.

[0118] The sound sensor 27 is equipped with an electret microphone, an amplification circuit, and a processing circuit.

After the voltage is processed by the amplification circuit and the processing circuit, the information is transmitted to the processor 4.

[0119] Furthermore, the processor 4 receives the signal transmitted by the acoustic wave detector 25.

[0125] A contact platform 37 is installed in the middle of the interior of the main body 1, a sealing tube 38 is installed in the middle of the interior of the main body 1, and a lifting element 39 is installed in the middle of the inner wall of the main body 1.

[0126] The processor 4 is connected to the environmental monitoring module 6 via wireless transmission. The environmental monitoring module 6 includes a temperature sensor 22, a humidity sensor 23, and a vibration sensor 24. The temperature sensor 22 is connected to the processor 4 via wireless transmission, the humidity sensor 23 is connected to the processor 4 via wireless transmission, and the vibration sensor 24 is connected to the processor 4 via wireless transmission.

[0127] The temperature sensor 22 is equipped with a thermistor, a conversion circuit and a processing unit. Based on the characteristic that the resistance value of the thermistor changes with temperature, when the ambient temperature changes, the resistance value of the thermistor decreases as the temperature rises and rises as the temperature falls. After the conversion circuit and processing unit convert and process the change in the resistance value of the thermistor, the current ambient temperature information is transmitted to the processor 4.

[0128] The humidity sensor 23 is equipped with a humidity-sensitive element, a processing circuit, and an output circuit. Based on the influence of humidity on the conductivity of materials, when the ambient humidity changes, the humidity-sensitive element absorbs hydrogen ions decomposed from water molecules in the air, causing a change in the resistance value of the humidity-sensitive element. The processing circuit receives and processes the change in resistance value, and the output circuit calculates the humidity in the current environment based on the change in resistance value, and transmits the information to the processor 4.

[0129] The vibration sensor 24 is equipped with a sensitive element, a conversion element, and a signal circuit. Based on the piezoelectric effect, when an object vibrates, the sensitive element is deformed by the external force, and polarization occurs inside, causing the two surfaces to have charges of opposite signs. After the external force is removed, the surface charges disappear and return to an uncharged state. The conversion element converts these charges into electrical signals. After the electrical signals are processed by the signal circuit, the acceleration of the vibration is calculated and transmitted to the processor 4.

[0130] Furthermore, the processor 4 receives information from the temperature sensor 22 and, after comparing it with a preset value, determines that the lead-acid battery needs heat exchange to balance its internal temperature. The processor 4 controls the lifting element 39 to drive the contact platform 37 to contact the exchanger 34, allowing the solution inside the reaction chamber 36 to enter the lead-acid battery through the sealing tube 38 for heat exchange. After heat exchange, the solution returns to the reaction chamber 36 through the sealing tube 38, thus realizing the function of controlling the internal temperature of the lead-acid battery. This prevents temperature imbalance inside the lead-acid battery, reduces its working efficiency, and affects the user experience, thereby extending the battery's lifespan and economic benefits.

[0131] Working principle: The processor 4 receives information from the temperature sensor 22. After comparing it with the preset value, it determines that the internal temperature of the lead-acid battery needs to be adjusted. The processor 4 controls the opening of the mixing valve 12 and the neutralization valve 15, so that the water stored in the water tank 13 is mixed with the solution in the neutralization tank 14 to generate heat through a neutralization reaction. The temperature probe measures the water temperature and transmits the data to the processor 4. After the standard temperature is reached, the mixing valve 12 is opened, and the water flows through the flow pipe 10 to cool the inside of the lead-acid battery. The processor 4 controls the neutralization valve 15 to connect the flow pipe 10 and the heat dissipation plate 16, so that the solution inside the neutralization tank 14 flows into the heat dissipation plate 16 to heat the inside of the lead-acid battery.

[0132] Temperature sensor 22 is based on the characteristic that the resistance value of a thermistor changes with temperature. When the ambient temperature changes, the resistance value of the thermistor decreases as the temperature rises and increases as the temperature falls. After conversion and processing by the conversion circuit and processing unit, the change in the resistance value of the thermistor is converted into a temperature change value and transmitted to processor 4. Humidity sensor 23 is based on the effect of humidity on the conductivity of materials. When the ambient humidity changes, the humidity-sensitive element absorbs hydrogen ions decomposed from water molecules in the environment, causing the resistance value of the humidity-sensitive element to change. The processing circuit and output circuit capture, convert, and process the change in the resistance value of the humidity-sensitive element to calculate the current humidity in the environment and transmit the information to processor 4. Vibration sensor 24 is based on the piezoelectric effect. When the lead-acid battery vibrates, the sensitive element is deformed by external force, and polarization occurs inside, causing opposite charges to appear on the two surfaces of the sensitive element. When the external force changes, the charge also changes. The conversion element and signal circuit capture, convert, and process the charge change, calculate the acceleration of the vibration, and transmit the signal to processor 4.

[0133] The acoustic detector 25 emits ultrasonic waves through an acoustic transmitter. The higher the electrolyte concentration, the faster the ultrasonic waves propagate. The processing circuit records the time it takes for the receiver to receive the reflected and transmitted ultrasonic waves. The processing circuit processes the information and calculates the electrolyte concentration by comparing it with the pre-stored temperature characteristic parameter curves of different media. The information is then transmitted to the processor 4. The tension sensor 26 is based on the resistance strain effect. When an external force is applied to the tension sensor 26, the elastic body deforms under the force, and the resistance strain gauge attached to the elastic body deforms accordingly. The measurement circuit captures, converts, amplifies, and processes the change in resistance value and then transmits the information to the processor 4. The sound sensor 27 moves the diaphragm inside the electret microphone with the sound wave, causing a change in the internal capacitance, which in turn generates a voltage change. The amplification circuit and processing circuit process the voltage change and then transmit the information to the processor 4.

[0134] After receiving the signals from the temperature sensor 22, the sound sensor 27 and the vibration sensor 24, the processor 4 compares them with the preset values ​​and determines that there is a fault inside the lead-acid battery, which needs to be dealt with. The processor 4 controls the isolation motor 31 to drive the push rod 32 to push the isolation plate 29 to isolate the inside of the lead-acid battery. The processor 4 controls the storage tank 30 to open, releasing the internal fire extinguishing material to fill the internal space of the lead-acid battery.

[0135] The processor 4 receives the signal transmitted by the acoustic wave detector 25. After comparing it with the preset value, it determines that the electrolyte concentration of the lead-acid battery needs to be adjusted. The processor 4 controls the mixing valve 12 to open, and adds water from the water tank 13 to the electrolyte through the flow pipe 10 to reduce the electrolyte concentration. The processor 4 controls the neutralization valve 15 to open, and adds the sulfuric acid stored inside to the electrolyte through the flow pipe 10 to increase the electrolyte concentration.
