[0002] A lithium battery block storage device is a device or system specifically designed for storing and preserving lithium battery blocks, and is designed to ensure the safety and stability of lithium battery blocks during storage.

[0003] Chinese patent CN215400619U discloses a storage device for lithium battery recycling, comprising a storage box, a storage drawer inside the storage box, and a storage device inside the storage drawer. The storage device includes a placement box and a protective device above the placement box. A placement cavity is centrally located on the upper surface of the placement box. Two side plates are symmetrically and movably arranged within the placement cavity. Multiple movable shafts are equidistantly fixed to the opposite sides of the two side plates. The ends of the multiple movable shafts away from the side plates extend out of the placement box, and springs are movably fitted onto the outer edges of the multiple movable shafts to abut against the side plates. A limiting circular plate is threadedly connected to the ends of the multiple movable shafts extending out of the placement box. A circular hole is provided inside the placement box for the movable shafts to extend out. This storage device for lithium battery recycling has a reasonable structure, facilitates the fixing of lithium batteries, and facilitates anti-oxidation protection of the electrode parts, making it highly practical.

[0004] However, existing technologies still have the following drawbacks: While existing technologies place the battery pack inside a storage box, the battery may self-discharge during storage, generating slight heat. Since the device does not cool the lithium battery, the temperature inside the storage box may rise, affecting the safety of battery storage. Therefore, we propose a storage device for lithium batteries to address this problem. Utility Model Content

[0007] The filter unit includes an air pump and an air inlet pipe. The air inlet pipe is fixedly connected to the inner wall of the box on the top surface of the box, and a sealing box is provided inside the air inlet pipe.

[0008] The box is equipped with a drying section;

[0009] The drying section includes a placement box, the interior of which is used to hold dehumidifying particles.

[0010] A further improvement is that the filtration section also includes a first partition, a spring, a mounting cylinder, a first filter screen, a third filter screen, an elastic pad, and a fixing plate. An air inlet is provided on the top surface of the housing, and a through hole is provided on the outer surface of the housing. The outer surface of the third filter screen is fixedly connected to the inner wall of the through hole. The first partition is fixedly sleeved on the outer surface of the air pump, and the outer surface of the first partition is fixedly connected to the inner wall of the housing. The air pump inlet pipe is located above the first partition, and the air pump outlet pipe is located below the first partition. By providing an air pump, it is convenient to drive the air body through the inside of the housing, which facilitates the heat dissipated by the battery.

[0011] A further improvement is that the outer surface of the mounting cylinder is provided with mounting holes, and the outer surface of the first filter screen is fixedly connected to the inner wall of the mounting cylinder. By setting the first filter screen and the mounting cylinder, it is convenient to filter impurities in the air.

[0012] A further improvement is that the outer surface of the mounting cylinder penetrates the air inlet and extends to the top of the housing. The outer surface of the mounting cylinder is threadedly connected to the inner wall of the housing. The fixing plate is fixedly sleeved on the outer surface of the top of the mounting cylinder. The top surface of the elastic pad is fixedly connected to the bottom surface of the fixing plate. The bottom surface of the elastic pad is pressed against the top surface of the housing.

This creates a negative pressure above the first partition, allowing external air to enter the housing. The airflow passes over the outer surface of the lithium battery, carrying away the heat emitted by the lithium battery and improving the safety of lithium battery storage. The first filter filters impurities in the airflow and collects them inside the mounting cylinder. To clean the inside of the mounting cylinder, simply rotate and remove the mounting cylinder. Simultaneously, the spring extends, causing the sealed box to move upwards, preventing air from entering through the air inlet pipe and avoiding impurities from falling onto the outer surface of the lithium battery, thus improving the safety of lithium battery storage. By setting up elastic pads and fixing plates, the mounting cylinder can be installed and removed by rotating it. The elastic pads prevent air from entering the box from the outside of the mounting cylinder. By setting up a second partition, a placement box, and a second filter, the second partition guides the airflow, allowing it to flow downwards through the placement box, facilitating a certain degree of dehumidification, reducing humidity control, and improving the safety of lithium battery storage.

The air inlet pipe of the air pump 211 is located above the first partition 212, and the air outlet pipe of the air pump 211 is located below the first partition 212.

[0027] The outer surface of the mounting cylinder 218 penetrates the air inlet and extends to the top of the housing 1. The outer surface of the mounting cylinder 218 is threaded to the inner wall of the housing 1. The outer surface of the mounting cylinder 218 is provided with mounting holes. The outer surface of the first filter screen 219 is fixedly connected to the inner wall of the mounting cylinder 218.

[0028] The bottom surface of the air inlet pipe 215 is fixedly connected to the top surface of the first partition 212. The outer surface of the sealing box 217 is slidably connected to the inner wall of the air inlet pipe 215. The bottom end of the spring 216 is fixedly connected to the top surface of the first partition 212, and the top end of the spring 216 extends into the interior of the sealing box 217 and is fixedly connected to the inner wall of the sealing box 217. By setting up the air pump 211, the first partition 212, the third filter 213, the air inlet pipe 215, the spring 216, the sealing box 217, the mounting cylinder 218, and the first filter 219, when the device is in use, the air pump 211 is started to make the first partition 212... A negative pressure is generated above plate 212, allowing outside air to enter the box 1. The airflow over the outer surface of the lithium battery carries away the heat emitted by the lithium battery, improving the safety of lithium battery storage. The first filter 219 filters impurities in the airflow and collects them inside the mounting cylinder 218. When cleaning the inside of the mounting cylinder 218, simply rotate and remove the mounting cylinder 218. At the same time, the spring 216 extends, causing the sealing box 217 to move upward, preventing air from entering through the air inlet pipe 215 and avoiding impurities from falling onto the outer surface of the lithium battery, thus improving the safety of lithium battery storage.

[0029] The fixing plate 201 is fixedly sleeved on the outer surface of the top end of the mounting cylinder 218.

The outer surface of the second filter 223 is fixedly connected to the inner wall of the air outlet. By setting the second partition 221, the placement box 222 and the second filter 223, the second partition 221 guides the air to flow downward through the interior of the placement box 222, which facilitates a certain degree of dehumidification of the air, reduces and controls humidity, and improves the safety of lithium battery storage.

[0034] When in use, start the air pump 211 to create negative pressure above the first air pump 212, which draws outside air into the housing 1. The air passes through the first filter 219 and the air pump 211 to reach the bottom of the first partition 212. Then the air passes through the dehumidifying particles inside the placement box 222 and reaches the bottom of the second partition 221, carrying away the heat emitted by the battery. Finally, it passes through the third filter 213 and is discharged from the housing 1.
