Abstract

The invention provides a lithium battery liquid leakage detection device; the lithium battery liquid leakage detection device comprises a detection sleeve; one end of the detection sleeve is open, the other end is hermetically connected with a detachable base; the matchup point of the base and the detection sleeve is provided with a liquid seal tank. In the provided lithium battery liquid leakage detection device, the detachable structure of the detection sleeve and the base provides convenience for inserting and taking out the tested battery, also provides convenience for detaching and cleaning the device; the arrangement of the sealing pad can further increase the airtightness of the device; when being used, the detection liquid contained in a tank overwhelms the tested battery and matches with the liquid seal tank, so as to check the airtightness of the device, thereby being able to solve the problem that the accuracy of detection is not high in the prior art; meanwhile, the lithium battery liquid leakage detection device has the advantages of simple in structure, low cost, and the like.

Description

technical field [0001] The invention relates to the field of battery sealing detection, in particular to a lithium battery leakage detection device. Background technique [0002] Lithium batteries have the advantages of high voltage, high specific energy, many cycle times, and long storage time. They are not only widely used in portable electronic devices such as mobile phones, digital cameras and laptop computers, but also widely used in electric vehicles and electric bicycles. And large and medium-sized electric equipment such as electric tools. The internal working environment of the lithium battery must be completely isolated from the external environment of the battery to ensure the normal operation of the battery. Technically, this is achieved by welding or colloidal sealing. The quality of the sealing directly determines whether the battery can work normally. [0003] If there is a problem with the sealing of the battery and the internal and external environments are...
