Description

Technical Field

[0001] This utility model belongs to the technical field of lithium battery discharge devices, specifically relating to a lithium battery material discharge treatment device. Background Technology

[0002] Lithium-ion batteries are batteries that use lithium metal or lithium alloy as the negative electrode material and a non-aqueous electrolyte solution. During the production, recycling, and research of lithium-ion batteries, it is often necessary to discharge the battery materials. This is because if lithium-ion batteries are not discharged during recycling, the electrical energy stored inside may cause the battery to overheat, catch fire, or even explode. Once a fire or explosion occurs, toxic and harmful substances in the battery, such as heavy metals like cobalt and nickel, as well as organic electrolytes, will be released into the environment, polluting soil and water sources, endangering ecological balance and human health. At the same time, undischarged lithium-ion batteries will interfere with subsequent physical sorting and chemical processing during recycling. Therefore, it is essential to discharge lithium-ion batteries using a dedicated discharge treatment device.

[0003] The existing discharge devices have a relatively simple overall structure, often simply connecting the battery to a discharge circuit with a high-precision resistor. This simple design has certain drawbacks in use. The quality of the recycled batteries is inconsistent, and heat is generated during the discharge process, so there is a risk of fire or explosion. The existing discharge devices do not have sufficient protective measures during the discharge process, and there are certain safety hazards for personnel during operation. Utility Model Content

[0034] A partition 600 is fixed inside the outer casing 100 and located below the placement rack assembly 300. A discharge module 700 is disposed on the surface of the partition 600. The discharge module 700 is electrically connected to the detection module 400. The discharge module 700 is composed of multiple switchable high-precision resistors. According to different lithium battery materials and discharge requirements, the appropriate resistance value can be selected by the control circuit of the control console 1100 to achieve precise discharge control.

[0035] A fan 800 is provided on the surface of the housing 100 and located on one side of the discharge module 700, and a heat dissipation hole 900 is provided on the surface of the housing 100 and located on the other side of the discharge module 700. The fan 800 and the heat dissipation hole 900 work together to provide air cooling for the inside of the housing 100.

[0036] The top cover assembly 1200 includes a top groove 1201 formed on the surface of the top plate 200 and an explosion-proof cover 1202 rotatably connected to the top port of the top groove 1201. When the explosion-proof cover 1202 is closed, it seals and protects the battery to prevent explosion.

[0037] In this embodiment, preferably, the placement rack assembly 300 further includes an induction plate 304, which is connected to the top of the electrode contact plate 303 and is inclined to facilitate sliding the electrode on the battery from top to bottom until it contacts the electrode contact plate 303.

[0040] In this embodiment, preferably, the limiting component 500 further includes a rubber pad 504, which is disposed on the surface of the pressing plate 503 to limit the compression of the battery and play a buffering and protective role.

[0041] In this embodiment, preferably, a water-cooling module 1000 is provided inside the outer shell 100 below the partition 600, which can perform water cooling to reduce the temperature inside the outer shell 100.

[0042] In this embodiment, preferably, the top cover assembly 1200 further includes a handle 1203, which is fixed to the surface of the explosion-proof cover 1202 to facilitate opening and closing of the explosion-proof cover 1202.

[0043] Working principle: When discharging lithium battery materials, the explosion-proof cover 1202 is opened first, and then the lithium battery materials are placed on the surface of the frame 301 through the top groove 1201, and the electrodes on the battery are brought into contact with the electrode contacts 303. Then, the explosion-proof cover 1202 is closed and the hydraulic rod 502 is activated to push the pressing plate 503 to move and squeeze the battery, thereby ensuring the stability of the battery during the discharge process and the connection stability between the electrodes and the electrode contacts 303. Then, the entire device is started by the control panel 1100, and the battery is discharged by the discharge module 700. The detection module 400 can detect the current, voltage and temperature during the discharge process to ensure the stability of the discharge. The exhaust fan 800 can blow air into the inside of the outer casing 100. The exhaust fan 800 and the heat dissipation hole 900 form an air duct to cool the temperature inside the outer casing 100. If the detection module 400 detects an abnormal temperature, the water cooling module 1000 is activated to perform emergency cooling inside the outer casing 100 to ensure safety.
