Technical Field
[0001] The utility model relates to the technical field of electrolyte detection tanks, in particular to an anti-collision and label leakage tank. Background Art
[0002] As one of the mainstream energy storage devices today, lithium batteries have been widely used in electric vehicles, wearable devices, mobile phones and other fields. However, with the large-scale application of lithium batteries, their safety and stability have become one of the issues that have received much attention. During the operation of the battery, electrolyte leakage may cause serious safety hazards, so the detection technology of electrolyte leakage is particularly important. The advantages of gas detection methods over other detection methods are its non-contact and real-time nature. It can monitor without destroying the battery structure, and sense electrolyte leakage in real time, which greatly reduces damage to the battery, and helps with early warning and reduces the possibility of accidents. In order to quantify the leakage of the electrolyte, we need to design an electrolyte detection tank with a standard leakage rate. However, the existing technology has the following shortcomings when used:
[0003] During the actual transportation and application of the leak-proof tank, the electrode liquid in the tank will occasionally collide with the breathable membrane at the tank mouth that regulates the volatilization rate of the electrolyte, causing damage to the breathable membrane and reducing the stability of the volatilization rate of the electrolyte and the stability of the breathable membrane.
[0004] Therefore, there is an urgent need for an anti-collision label leakage tank to solve the above problems. Utility Model Content
[0005] The purpose of the utility model is to address the problem that in the actual transportation and application of the existing standard leakage tank, the electrode liquid in the tank will occasionally collide with the breathable membrane at the tank mouth that regulates the volatilization rate of the electrolyte, causing damage to the breathable membrane and reducing the stability of the volatilization rate of the electrolyte and the stability of the breathable membrane.
[0006] In order to achieve the above-mentioned invention object, the utility model provides the following technical solutions:
[0007] The invention discloses an anti-collision and label leakage tank to improve the above problems.
[0008] The specific application is as follows:

[0015] As a preferred technical solution of the present application, the standard sample storage tank is made of stainless steel.
[0016] Compared with the prior art, the utility model has the following beneficial effects:
[0017] In the scheme of this application:
[0018] The stainless steel funnel is provided, and the structure of the stainless steel funnel is thin at the lower end and thick at the upper end. The advantage of this structural design is that, without changing the DMC partial pressure of the electrolyte in the standard storage tank, the thin opening at the lower end of the funnel structure can effectively prevent the electrolyte in the tank from directly colliding with the PTFE permeable membrane. Under severe impact, the electrolyte in the standard storage tank will rotate back and forth along the inner wall of the tank body and the outer arc surface of the stainless steel funnel, and will not pass through the lower end of the stainless steel funnel and directly contact the PTFE permeable membrane, thereby preventing the electrolyte from directly causing mechanical damage to the PTFE permeable membrane, thereby improving the stability and life of the PTFE permeable membrane, and solving the problem that in the actual transportation and application of the leaky tank in the prior art, the electrode liquid in the tank will occasionally collide with the breathable membrane at the tank mouth that regulates the volatilization rate of the electrolyte, causing damage to the breathable membrane, reducing the stability of the volatilization rate of the electrolyte and the stability of the breathable membrane.

[0030] Example:
[0031] like Figure 1-4As shown, the present embodiment proposes an anti-collision and leakage-proof tank, comprising a standard sample storage tank 1, a KF flange bottle mouth 2 is provided on the standard sample storage tank 1, a connecting cavity 3 is opened on the KF flange bottle mouth 2, a stainless steel gasket 4 and a PTFE permeable membrane 5 are arranged in the connecting cavity 3, a permeable membrane fixing nut 6 is arranged at the bottom of the PTFE permeable membrane 5, an anti-collision funnel nut 7 is arranged in the connecting cavity 3, a stainless steel funnel 8 is fixedly connected to the bottom of the anti-collision funnel nut 7, and the stainless steel funnel 8 has a thin lower end and a thick upper end opening. The advantage of this structural design is that, without changing the DMC partial pressure of the electrolyte in the standard sample storage tank 1, the thin mouth at the lower end of the funnel structure can effectively prevent the electrolyte in the tank from directly colliding with the PTFE permeable membrane 5, thereby reducing the mechanical damage to the PTFE permeable membrane 5 caused by the collision of the electrolyte during actual application, thereby improving the stability and service life of the PTFE permeable membrane 5.
[0032] like Figure 4 As shown, a placement groove 9 is provided on the top of the KF flange bottle mouth 2, and a stainless steel sinter 10 is provided in the placement groove 9.
[0033] like Figure 3 and Figure 4 As shown, the PTFE permeable membrane 5 is consistent in size with the stainless steel gasket 4 .
[0034] like Figure 3 and Figure 4 As shown, the standard sample storage tank 1, the stainless steel gasket 4, the PTFE permeable membrane 5 and the permeable membrane fixing nut 6 are sealed by vacuum glue. After the glue sealing is complete, a heavy object is placed on the stainless steel gasket 4 to make the contact surface fit tightly, and the obtained device is dried in an oven to solidify the vacuum glue.
[0035] like Figure 4 As shown, the stainless steel funnel 8 is welded to the inner wall of the tank mouth of the standard sample storage tank 1 to fix the stainless steel funnel 8.
[0036] like Figure 1 As shown, the top side of the outer wall of the standard sample storage tank 1 is an arc-shaped surface.
[0037] like Figure 1 As shown, the standard sample storage tank 1 is made of stainless steel to ensure the service life of the standard sample storage tank 1.
[0038] Specifically, when the anti-collision and leakage-proof tank is in use, the stainless steel funnel 8 has a thin lower end and a thick upper opening. The advantage of this structural design is that, without changing the DMC partial pressure of the electrolyte in the standard sample storage tank 1, the thin opening at the lower end of the funnel structure can effectively prevent the electrolyte in the tank from directly colliding with the PTFE permeable membrane 5. During actual transportation and application of the standard sample storage tank 1, if it is subjected to a severe collision, the electrolyte in the standard sample storage tank 1 will rotate back and forth along the inner wall of the tank body and the outer arc surface of the stainless steel funnel 8, and will not pass through the lower end of the stainless steel funnel 8 and directly contact the PTFE permeable membrane 5, thereby preventing the electrolyte from directly causing mechanical damage to the PTFE permeable membrane 5, thereby improving the stability and life of the PTFE permeable membrane 5.
