Description

Technical Field

[0001] This utility model relates to the field of battery technology, and in particular to a storage device for battery materials. Background Technology

[0002] Lithium-ion battery electrolytes, acting as ion transport carriers, are one of the key raw materials for batteries. The electrolyte plays a crucial role in conducting ions between the positive and negative electrodes of a lithium battery. It is generally prepared under specific conditions and in specific proportions using high-purity organic solvents, lithium electrolyte salts, and necessary additives. After production, the battery electrolyte requires proper storage, especially to prevent deterioration due to excessively high temperatures or solidification due to excessively low temperatures.

[0003] In related technologies, cooling pipes are installed inside the electrolyte tank to cool the electrolyte. However, since the cooling pipes are in direct contact with the electrolyte, there is a risk of pipe damage and electrolyte leakage. Utility Model Content

[0004] The main purpose of this invention is to provide a battery material storage device that effectively regulates the electrolyte temperature, prevents the electrolyte temperature from being too high or too low, and reduces the risk of electrolyte leakage.

[0005] To achieve the above objectives, the present invention provides a battery material storage device comprising:

[0006] First container;

[0007] A second container, disposed within the first container, is used to store the electrolyte; and

[0008] A cooling system is provided between the first container and the second container; the cooling system includes a cooling pipe and a heat exchange pipe assembly, the heat exchange pipe assembly being connected to the cooling pipe to form a coolant circulation loop; the cooling pipe is provided on the outer wall of the second container and is configured to exchange heat with the electrolyte inside the second container.

[0009] In the battery material storage device of this utility model, a cooling system is installed inside the first container. This cooling system is located outside the second electrolyte container and will not come into direct contact with the electrolyte, thus avoiding corrosion and eliminating the risk of leakage. At the same time, the cooling system includes a cooling pipe disposed on the outer wall of the second container and a heat exchange pipeline assembly connected to the cooling pipe. The heat exchange pipeline assembly can form a coolant circulation loop with the cooling pipe, using the circulating flow of coolant to cool or heat the electrolyte in the second container, so that the electrolyte in the second container is at a suitable temperature and not too high or too low. Therefore, the storage quality of the electrolyte can be guaranteed and the storage time can be extended.

[0010] In one embodiment of this application, the heat exchange piping assembly includes:

[0011] The heat exchange pipeline is connected to the cooling pipe to form the coolant circulation loop;

[0012] A heat exchanger, connected in series with the heat exchange piping, is configured to exchange heat with the heat exchange piping; and

[0013] A drive component, connected to the heat exchange pipeline, is configured to drive the coolant to circulate in the coolant circulation loop.

[0014] In this design, the heat exchanger regulates the temperature of the coolant within the heat exchange pipes, and the drive component circulates the coolant within the coolant circulation loop. When cooling is required, the coolant absorbs heat from the electrolyte at the cooling pipes and then flows to the heat exchanger to dissipate heat and cool down. The cooled coolant can then flow back into the cooling pipes to cool the electrolyte. When heating is required, the coolant releases heat to the electrolyte at the cooling pipes and then flows to the heat exchanger to absorb heat and heat up. The cooled coolant can then flow back into the cooling pipes to heat up the electrolyte, thus achieving the purpose of coolant recycling.

[0015] In one embodiment of this application, the heat exchange pipeline assembly further includes a housing for storing coolant and communicating with the heat exchange pipeline. In the coolant circulation loop, the housing is located downstream of the heat exchanger and upstream of the cooling pipe.

[0016] This design allows the coolant to be stored in the tank when the electrolyte temperature does not need to be adjusted, eliminating the need for circulation. Only when the electrolyte temperature needs to be adjusted will the coolant flow out of the tank for circulation under the drive of the drive components. This saves energy, reduces power consumption, reduces heat loss of the coolant, and improves the heat exchange efficiency between the coolant and electrolyte in the cooling pipes.

[0017] In one embodiment of this application, the first container has an installation cavity below the second container, and the heat exchange pipeline assembly is located in the installation cavity.

[0018] This design makes full use of the space below the second container, making the internal structure of the first container more compact and regular, reducing the horizontal space occupied, and reducing the overall horizontal size of the first container.

[0019] In one embodiment of this application, the cooling pipe is arranged in a tortuous coil shape on the outer wall of the second container.

[0020] This design increases the heat exchange area between the cooling pipe and the second container, thereby improving the heat exchange efficiency between the coolant and the electrolyte.

[0021] In one embodiment of this application, the cooling pipe is attached to one side wall of the second container, and the inlet and outlet ends of the cooling pipe extend downward along the wall of the second container into the mounting cavity and are connected to the heat exchange pipeline assembly.

[0022] This design simplifies the connection structure between the cooling pipes and the heat exchange pipe assembly, avoids complicated pipe routing, and further reduces the space occupied and the overall size of the unit.

[0023] In one embodiment of this application, the first container is provided with a plurality of heat dissipation holes at the position corresponding to the mounting cavity.

[0024] This design facilitates air circulation inside and outside the first container, preventing electrical components from overheating.

[0025] In one embodiment of this application, the cooling system further includes:

[0026] The control module, located in the first container, is electrically connected to the drive component; and

[0027] A temperature sensor, installed in the second container, is configured to detect the temperature of the electrolyte inside the second container; the temperature sensor is electrically connected to the control module.

[0028] This design enables automatic detection and adjustment of the electrolyte temperature in the second container without manual operation, reducing labor intensity and achieving precise temperature control of the electrolyte in the second container.

[0029] In one embodiment of this application, the battery material storage device further includes a battery module disposed in the first container, the battery module being electrically connected to both the drive component and the control module.

[0030] This design allows the storage device for the battery material to operate without an external power source, enabling it to adapt to more application scenarios and achieve independent temperature control.

[0031] In one embodiment of this application, the bottom wall of the first container is provided with a plurality of limiting blocks, and the plurality of limiting blocks abut against and limit the side wall of the battery module.

[0032] This design can fix and limit the battery module, preventing shaking or displacement that may occur during transportation or use, and also ensures the stability and reliability of the connection between the battery module and the first container.

[0033] In one embodiment of this application, the top of the first container is provided with a feed pipe, which is connected to the second container; and / or, the side wall of the first container is provided with a discharge pipe, which is connected to the lower part of the inner cavity of the second container.

[0034] This design improves the ease of liquid inlet and outlet operations.

[0050] Currently, the application of power batteries is becoming increasingly widespread. Power batteries are not only used in energy storage power systems such as hydropower, thermal power, wind power, and solar power plants, but also widely used in electric vehicles such as electric bicycles, electric motorcycles, and electric cars, as well as in aerospace and other fields. With the continuous expansion of the application areas of power batteries, the market demand is also constantly increasing.

[0051] Lithium-ion batteries are a crucial power source for electric vehicles and other electrical devices. Lithium-ion battery electrolytes, acting as ion transport carriers, are one of the key raw materials for batteries. The electrolyte plays a vital role in conducting ions between the positive and negative electrodes of a lithium battery. It is generally prepared under specific conditions and in specific proportions using high-purity organic solvents, lithium electrolyte salts, and necessary additives. After production, the battery electrolyte requires proper storage and treatment, especially to prevent deterioration due to excessively high temperatures or solidification due to excessively low temperatures.

[0052] In related technologies, cooling pipes are installed inside the electrolyte tank to cool the electrolyte. However, since the cooling pipes are in direct contact with the electrolyte, there is a risk of pipe damage and electrolyte leakage.

[0053] Therefore, this utility model proposes a battery material storage device, which aims to effectively regulate the electrolyte temperature by setting a coolant circulation loop outside the second container, preventing the electrolyte temperature from being too high or too low, and reducing the risk of electrolyte leakage. The structure of this battery material storage device will be described below by way of embodiments.

[0054] like Figures 1 to 3 As shown, the storage device for the battery material includes a first container 1, a second container 2, and a cooling system 3.

[0055] The second container 2 is located inside the first container 1 and is used to store electrolyte. The cooling system 3 is located between the first container 1 and the second container 2. The cooling system 3 includes a cooling pipe 31 and a heat exchange pipe assembly 32. The heat exchange pipe assembly 32 is connected to the cooling pipe 31 to form a coolant circulation loop. The cooling pipe 31 is located on the outer wall of the second container 2 and is configured to exchange heat with the electrolyte inside the second container 2.

[0056] The first container 1 houses and installs the second container 2, cooling system 3, and other components, serving as a protective shell. It can be a fully enclosed or partially enclosed structure. In practical applications, the first container 1 can be a cuboid, cube, cylinder, or other shapes, and can be made of metallic or non-metallic materials. Optionally, the first container 1 includes a shell and a top cover installed at the top opening of the shell. The second container 2 is installed inside the shell through an opening in the shell and sealed by the top cover. This not only ensures a secure and reliable installation but also facilitates user removal and cleaning of the cover, maintaining the cleanliness and hygiene of the battery material storage device.

[0057] The second container 2 is located inside the first container 1 and is used to store the electrolyte. Understandably, to facilitate cooling of the electrolyte inside, the second container 2 can be made of a material with high thermal conductivity, corrosion resistance, and resistance to reaction with the electrolyte, such as stainless steel. In practical applications, the second container 2 can be a cuboid, cube, cylinder, or other shapes. Optionally, the shape of the second container 2 can be similar to that of the first container 1 to facilitate a more stable and reliable installation of the second container 2 within the first container 1.

[0058] The cooling system 3 is located between the first container 1 and the second container 2. It can exchange heat with the electrolyte inside the second container 2, ensuring that the temperature of the electrolyte inside the second container 2 is at a suitable level, neither too high nor too low, thus guaranteeing the storage quality and storage time of the electrolyte. It should be noted that the cooling system 3 is located outside the second container 2. On the one hand, it does not occupy the electrolyte storage space, increasing the storage capacity; on the other hand, it isolates itself from the electrolyte, preventing corrosion, eliminating the risk of leakage, and improving equipment safety and service life.

[0059] Cooling system 3 includes cooling pipe 31 and heat exchange pipe assembly 32. The heat exchange pipe assembly 32 is connected to cooling pipe 31 to form a coolant circulation loop. Cooling pipe 31 is located on the outer wall of the second container 2 and is configured to exchange heat with the electrolyte in the second container 2. Thus, when the temperature of the electrolyte in the second container 2 is too high, the coolant in the coolant circulation loop can exchange heat with the electrolyte in the second container 2 as it flows through cooling pipe 31, absorbing and carrying away the heat from the electrolyte. The coolant that has absorbed heat can flow into heat exchange pipe assembly 32 to dissipate heat, and the cooled coolant can flow back through cooling pipe 31. The system absorbs heat from the electrolyte, and this cycle repeats continuously to cool the electrolyte and prevent it from overheating and deteriorating. When the electrolyte temperature in the second container 2 is too low, the coolant in the cooling circulation loop can exchange heat with the electrolyte in the second container 2 as it flows through the cooling pipe 31, transferring heat to the electrolyte. The coolant that has released heat can flow into the heat exchange pipe assembly 32 to absorb heat, and the cooled coolant that has absorbed heat can flow through the cooling pipe 31 again to release heat to the electrolyte. This cycle repeats continuously to heat the electrolyte and prevent it from solidifying due to overcooling, thus improving the practicality of the device.

[0060] In practical applications, the cooling pipe 31 can be installed only on a portion of the outer wall of the second container 2 or surrounding the entire outer perimeter of the second container 2. Specifically, it can be installed on the outer wall of the second container 2 in a tortuous coiled shape, a stacked shape, or some other manner to increase the heat exchange area between the cooling pipe 31 and the second container 2. Optionally, the cooling pipe 31 can be connected to the outer wall of the second container 2 by means of attachment, embedding, welding, or winding. Optionally, the cooling pipe 31 can be made of copper, aluminum, or other structures with high thermal conductivity. The cross-sectional shape of the cooling pipe 31 can be determined according to the actual situation, such as circular, rectangular, triangular, or other irregular shapes.

[0061] The specific structure of the heat exchange piping assembly 32 can be determined according to the actual situation. For example, it can be a combination of heat exchange piping 321, heat exchanger 322 and drive pump, or it can be a refrigeration system or heat pump system, as long as it can realize the circulation of coolant between the heat exchange piping assembly 32 and cooling pipe 31, and can regulate the temperature of coolant in the heat exchange piping assembly 32. Optionally, the coolant can be water or other fluids.

[0062] In summary, in the battery material storage device of this utility model, a cooling system 3 is installed inside the first container 1. This cooling system 3 is located outside the second electrolyte container 2 and will not come into direct contact with the electrolyte, thus avoiding corrosion and eliminating the risk of leakage. At the same time, the cooling system 3 includes a cooling pipe 31 disposed on the outer wall of the second container 2 and a heat exchange pipeline assembly 32 connected to the cooling pipe 31. The heat exchange pipeline assembly 32 can form a coolant circulation loop with the cooling pipe 31, using the circulating flow of coolant to cool or heat the electrolyte in the second container 2, so that the electrolyte in the second container 2 is at a suitable temperature and not too high or too low. Therefore, the storage quality of the electrolyte can be guaranteed and the storage time can be extended.

[0063] Please see Figure 2 and Figure 3 In one embodiment of this application, the heat exchange pipeline assembly 32 includes a heat exchange pipeline 321, a heat exchanger 322, and a drive component 323. The heat exchange pipeline 321 is connected to the cooling pipe 31 to form a coolant circulation loop; the heat exchanger 322 is connected in series with the heat exchange pipeline 321 and is configured to exchange heat with the heat exchange pipeline 321; the drive component 323 is connected to the heat exchange pipeline 321 and is configured to drive the coolant to circulate in the coolant circulation loop.

[0064] The heat exchange pipe 321 can be understood as a connecting pipe structure for circulating coolant. The inlet of the heat exchange pipe 321 is connected to the outlet of the cooling pipe 31, and the outlet of the heat exchange pipe 321 is connected to the inlet of the cooling pipe 31 to form a coolant circulation loop. Optionally, the heat exchange pipe 321 can be a flexible hose structure, which is easy to bend and adapt to the structural layout. The heat exchange pipe 321 can be made of metallic or non-metallic materials. The heat exchange pipe 321 and the cooling pipe 31 can be connected by welding, clamping, screwing, or connecting joints.

[0065] Heat exchanger 322 is connected in series with heat exchange pipe 321. This can be understood as heat exchanger 322 having internal flow channels that communicate with heat exchange pipe 321, allowing the coolant in heat exchange pipe 321 to exchange heat with heat exchanger 322 as it flows through these internal channels. Alternatively, heat exchanger 322 may not have internal flow channels and may be located outside heat exchange pipe 321, such as being sleeved around the periphery of heat exchange pipe 321 or attached to its side wall, allowing the coolant to exchange heat with heat exchanger 322 as it flows through heat exchange pipe 321. Optionally, heat exchanger 322 can be a plate heat exchanger, finned heat exchanger, shell-and-tube heat exchanger, or other types of heat exchanger 322.

[0066] The drive component 323 is connected to the heat exchange pipe 321 and provides power for the circulation of coolant in the coolant circulation loop. Optionally, the drive component 323 can be a liquid pump.

[0067] In this embodiment, the heat exchange pipe 321 is connected to the cooling pipe 31 to form a coolant circulation loop. By setting a heat exchanger 322 and a driving component 323 on the heat exchange pipe 321, the heat exchanger 322 can regulate the temperature of the coolant in the heat exchange pipe 321, and the driving component 323 can drive the coolant to circulate in the coolant circulation loop. When cooling is required, the coolant absorbs heat from the electrolyte at the cooling pipe 31 and then flows to the heat exchanger 322 to dissipate heat and cool down. The cooled coolant can then flow back into the cooling pipe 31 to cool the electrolyte. When heating is required, the coolant releases heat to the electrolyte at the cooling pipe 31 and then flows to the heat exchanger 322 to absorb heat and heat up. The cooled coolant can then flow back into the cooling pipe 31 to heat up the electrolyte, thus achieving the purpose of coolant recycling.

[0068] Please see Figures 2 to 4 In one embodiment of this application, the heat exchange pipeline assembly 32 further includes a housing 324 for storing coolant, the inlet of the housing 324 being connected to the outlet of the heat exchange pipeline 321, and the outlet of the housing 324 being connected to the inlet of the heat exchange pipeline 321.

[0069] The housing 324 serves to store the coolant and can be rectangular, cubic, cylindrical, or other shapes. It can be made of metallic or non-metallic materials. To ensure better heat exchange, the housing 324 can be made of or wrapped with insulation material to prevent heat loss from the internal coolant. The inlet of the housing 324 is connected to the outlet of the heat exchange pipe 321, and the outlet of the housing 324 is connected to the inlet of the heat exchange pipe 321, thus creating a coolant circulation loop. The drive component 323 drives the coolant inside the housing 324 to flow through the heat exchange pipe 321 and cooling pipe 31 before returning to the housing 324. Optionally, the housing 324 and the heat exchange pipe 321 can be installed by welding, snap-fitting, screwing, or connecting joints.

[0070] With this design, when the electrolyte temperature does not need to be adjusted, the coolant can be stored in the housing 324 without circulation. Only when the electrolyte temperature needs to be adjusted will the coolant flow out of the housing 324 for circulation under the drive of the drive component 323. This saves energy and reduces power consumption.

[0071] Please see Figure 4 In some embodiments, the upper surface of the housing 324 is provided with a fixedly connected filling pipe 3241, and the top end of the filling pipe 3241 is connected to a pipe cap. The design of the pipe cap allows the user to easily open or close the filling pipe 3241. When it is necessary to add coolant to the housing 324, the user only needs to unscrew the pipe cap to inject coolant into the housing 324 through the filling pipe 3241. When it is not necessary to add liquid, the user can tighten the pipe cap to prevent dust and debris from entering the housing 324, thus keeping the housing 324 clean and hygienic.

[0072] Please see Figures 2 to 4 In one embodiment of this application, in the coolant circulation loop, the housing 324 is located downstream of the heat exchanger 322 and upstream of the cooling pipe 31.

[0073] In this embodiment, by placing the housing 324 between the heat exchanger 322 and the cooling pipe 31, the coolant after its temperature has been adjusted by the heat exchanger 322 can quickly flow into the housing 324 for heat preservation and storage. When it is necessary to adjust the electrolyte temperature, the coolant flowing out of the housing 324 can first flow through the cooling pipe 31 to exchange heat with the electrolyte in the second container 2, which shortens the flow path of the coolant before it enters the cooling pipe 31, reduces the heat loss of the coolant, and improves the heat exchange efficiency between the coolant and the electrolyte in the cooling pipe 31.

[0074] Please see Figures 2 to 5 In one embodiment of this application, the first container 1 is provided with an installation cavity 101 below the second container 2, and the heat exchange pipeline assembly 32 is located in the installation cavity 101.

[0075] Understandably, the housing 324, heat exchanger 322, drive component 323, and heat exchange pipeline 321 are all located in the mounting cavity 101 below the second container 2. This design can make full use of the space below the second container 2, making the internal structure of the first container 1 more compact and regular, reducing the lateral space occupied, and reducing the overall lateral size of the first container 1.

[0076] Please see Figure 3 In one embodiment of this application, the cooling pipe 31 is in the shape of a tortuous coil. The cooling pipe 31 is attached to one side wall of the second container 2. The inlet end and outlet end of the cooling pipe 31 extend downward along the wall of the second container 2 into the mounting cavity 101 and are connected to the heat exchange pipeline assembly 32.

[0077] This design can, on the one hand, increase the heat exchange area between the cooling pipe 31 and the second container 2, and improve the heat exchange efficiency between the coolant and the electrolyte; on the other hand, the inlet and outlet ends of the cooling pipe 31 extend downward along the wall of the second container 2 into the mounting cavity 101 and connect with the heat exchange pipeline assembly 32, which can simplify the connection structure between the cooling pipe 31 and the heat exchange pipeline assembly 32, avoid complicated pipe routing, and further reduce the space occupied and the overall size of the machine.

[0078] As an example, the inlet end of the cooling pipe 31 extends downward to connect with the housing 324; the outlet end of the cooling pipe 31 extends downward to connect with the drive component 323.

[0079] Please see Figure 5 In one embodiment of this application, the first container 1 is provided with a plurality of heat dissipation holes 102 at the position corresponding to the mounting cavity 101.

[0080] In this embodiment, the heat dissipation hole 102 facilitates air circulation inside and outside the first container 1. By setting the heat dissipation hole 102 to correspond to the mounting cavity 101, the heat generated by the heat exchange pipeline assembly 32 can be dissipated to the external environment more quickly from the heat dissipation hole 102, preventing the electrical components from overheating.

[0081] Optionally, the number of heat dissipation holes 102 can be one, two, or more. When there are multiple heat dissipation holes 102, the multiple heat dissipation holes 102 can be arranged at intervals to make heat dissipation more uniform.

[0082] In some embodiments, a filter screen is provided at the heat dissipation hole 102 to prevent dust and debris from entering the first container 1.

[0083] Please see Figure 3 and Figure 4In one embodiment of this application, the cooling system 3 further includes a control module 33 and a temperature sensor 34. The control module 33 is located in the first container 1 and is electrically connected to the drive component 323. The temperature sensor 34 is installed in the second container 2 and is configured to detect the temperature of the electrolyte in the second container 2. The temperature sensor 34 is electrically connected to the control module 33.

[0084] Among them, the control module 33 can be the electronic control system of the battery material storage device, which can control the start, stop and adjust the operating power of the drive component 323.

[0085] Temperature sensor 34 is installed in the second container 2, specifically, the sensing end of temperature sensor 34 can extend into the second container 2 to monitor the electrolyte temperature. Temperature sensor 34 is electrically connected to control module 33 to monitor the temperature change of the electrolyte inside the second container 2 in real time. Once the electrolyte temperature exceeds the preset safety range, temperature sensor 34 will immediately send a signal to control module 33, and control module 33 will automatically activate corresponding heat dissipation measures to adjust the electrolyte temperature to the safe range.

[0086] In this embodiment, when the temperature sensor 34 detects that the electrolyte temperature in the second container 2 is too high, the control module 33 controls the drive component 323 to start, extracting the coolant from the tank 324 and delivering it to the cooling pipe 31 on the outer surface of the second container 2 to cool the electrolyte in the second container 2. The cooled coolant, after absorbing heat, is cooled by the heat exchanger 322 and then returns to the tank 324 for recycling. At the same time, the temperature sensor 34 monitors the temperature of the electrolyte in the second container 2 and transmits the temperature information to the control module 33. The control module 33 controls the power of the drive component 323 to control the flow rate of the coolant, thereby achieving the purpose of controlling the electrolyte temperature. When the temperature reaches the target, the control module 33 controls the drive component 323 to stop, avoiding energy waste.

[0087] This design enables automatic detection and adjustment of the electrolyte temperature in the second container 2 without manual operation, reducing labor intensity and achieving precise temperature control of the electrolyte in the second container 2.

[0088] Please see Figure 1 In one embodiment of this application, the first container 1 is equipped with an interactive display module 6, which allows users to view the electrolyte temperature information in real time and control the control module 33. This design not only improves the intelligence of the battery material storage device but also facilitates remote monitoring and operation by users, ensuring the safety and reliability of the electrolyte storage process.

[0089] Please see Figures 3 to 5In one embodiment of this application, the battery material storage device further includes a battery module 4 disposed in the first container 1, and the battery module 4 is electrically connected to the drive component 323 and the control module 33.

[0090] In this embodiment, the battery module 4 can independently provide power to the drive component 323, the control module 33, and the interactive display module 6, ensuring independent operation. This design allows the storage device for the battery material to operate without an external power source, enabling it to adapt to more application scenarios and achieve independent temperature control.

[0091] Please see Figure 2 and Figure 3 In one embodiment of this application, the bottom wall of the first container 1 is provided with a plurality of limiting blocks 11, and the plurality of limiting blocks 11 abut against and limit the side wall of the battery module 4.

[0092] The limiting block 11 can be a rectangular block, a square block, a ring block, or some other shape. The number of limiting blocks 11 can be determined according to the actual situation. For example, it can be a ring block structure with a receiving groove, or it can be two or more limiting blocks 11 combined to form a receiving groove, etc. As an example, this embodiment has two limiting blocks 11 arranged opposite to each other. The side of the two limiting blocks 11 that are close to each other abuts against the opposite side walls of the battery module 4, thereby realizing the clamping and limiting function of the battery module 4.

[0093] This design can fix and limit the battery module 4, preventing shaking or displacement that may occur during transportation or use, and also ensures the stability and reliability of the connection between the battery module 4 and the first container 1.

[0094] Optionally, the control module 33 is installed on the side of the limit block 11 away from the battery module 4.

[0095] Please see Figure 1 and Figure 4 In one embodiment of this application, the top of the first container 1 is provided with a feed pipe 51, which is connected to the second container 2; and / or, the side wall of the first container 1 is provided with a discharge pipe 52, which is connected to the lower part of the inner cavity of the second container 2.

[0096] In this embodiment, a feed pipe 51 is provided at the top of the first container 1. The feed pipe 51 passes through the first container 1 and communicates with the second container 2, for supplying electrolyte into the second container 2. By placing the feed pipe 51 at the top of the first container 1, the gravity of the electrolyte can be fully utilized, reducing flow resistance and allowing the electrolyte to flow into the second container 2 more quickly. Optionally, a valve is provided inside the feed pipe 51 to control the opening and closing of the feed pipe 51, effectively preventing electrolyte leakage and ensuring the safety and environmental friendliness of the storage process.

[0097] In this embodiment, a discharge pipe 52 is provided on the side wall of the first container 1. The discharge pipe 52 passes through the lower inner cavity of the first container 1 and communicates with the lower inner cavity of the second container 2 to facilitate electrolyte discharge. By communicating the discharge pipe 52 with the lower inner cavity of the second container 2, the electrolyte discharge efficiency can be improved. Optionally, a valve is provided inside the discharge pipe 52. When it is necessary to discharge the electrolyte, the user only needs to open the valve of the discharge pipe 52, and the electrolyte can be discharged smoothly.

[0098] This design not only improves ease of operation but also effectively prevents electrolyte leakage, ensuring the safety and environmental friendliness of the storage process.
