Description

Technical Field

[0001] The invention relates to the field of lubricating grease, and in particular to a new energy vehicle battery box test tube. Background Art

[0002] The internal working environment of lithium-ion batteries must be completely isolated from the external environment of the battery to ensure the normal operation of the battery. Technically, this is achieved through welding or colloid sealing. The quality of the sealing directly determines whether the battery can work normally. If there is a problem with the battery sealing, the electrolyte and gas inside the battery will leak out, and the air and moisture in the environment will enter the battery and participate in the electrochemical reaction, causing the battery to fail. Taking polymer lithium-ion batteries as an example, the isolation of the internal and external environments of the battery is achieved by bonding the inner layer of polypropylene glue of a layer of aluminum-plastic packaging film. This method can isolate the electrode materials, electrolytes, gases in the working environment inside the battery from the air, moisture, dust, etc. in the external environment. If the adhesive layer of the aluminum-plastic packaging film has a poor bonding effect, causing the internal and external environments to communicate, it will cause the electrolyte inside the battery to leak out (leakage), air to enter the battery, causing the battery to bulge, and the loss of charging and discharging functions. Leakage is defined by the customer as a non-compliant type.

[0003] The electrolyte is one of the four key materials of lithium-ion batteries (positive electrode, negative electrode, separator, and electrolyte). It is known as the "blood" of lithium-ion batteries. It plays the role of conducting electrons between the positive and negative electrodes in the battery and is the guarantee for lithium-ion batteries to obtain advantages such as high voltage and high specific energy. The electrolyte is generally made of high-purity organic solvents, electrolyte lithium salts (lithium hexafluorophosphate, LiFL6), necessary additives and other raw materials, prepared in a certain proportion under certain conditions.

[0004] With the development of polymer battery technology and the continuous improvement of customer requirements, leakage has become a difficult point in polymer battery quality control and a carrier of core competitiveness of product quality. How to prevent the generation of leaking batteries and possibly prevent leaking batteries from flowing out to customers has become an important direction of competition among battery manufacturers.

[0010] Further configuration: both ends of the main discharge pipe are provided with threaded sealing protection rings.

[0011] By adopting the above technical solution, the threaded sealing protection rings arranged at both ends of the discharge main pipeline can ensure the safety and stability of the electrolyte.

[0012] It is further provided that: a first mounting ring and a second mounting ring are sleeved on the surface of the main discharge pipe, and a mounting frame fixedly connected to the bottom of the first mounting ring and the second mounting ring is provided.

[0013] By adopting the above technical solution, the first mounting ring and the second mounting ring located on the surface of the main material main pipeline and the fixedly connected mounting frame at the bottom are used to fix and support the entire discharge pipe fitting, which can safely and stably support the normal operation of the discharge pipe fitting above.

[0014] It is further arranged that: a plurality of pressure relief holes are arranged on the surface of the main discharge pipe, and pressure regulating plugs are arranged on the surfaces of a plurality of the pressure relief holes.

[0015] By adopting the above technical solution, when the value on the surface of the pressure display shows that the internal pressure value is too large, the pressure can be released through the pressure regulating plug arranged on the pressure relief hole on the discharge main pipeline, avoiding safety hazards.

[0016] It is further provided that: a plurality of threaded holes are provided on the surface of the mounting frame, and threaded fastening bolts are provided in the threaded holes.
