Abstract

The invention discloses a leak-detecting device of a super capacitor, comprising a leak-detecting cavity (3), wherein the top opening of the leak-detecting cavity (3) is communicated with a super capacitor (1); the upper end and the lower end of the right side wall of the leak detection cavity (3) are respectively communicated with a helium mass spectrometer (5) and a vacuum pump (4); an air blow pipe (60) is arranged above the super capacitor (1); and the air blow pipe (60) is communicated with a helium source (6). The leak detection device of a super capacitor, which is disclosed by the invention, has the advantages of higher measuring precision and wider measuring range and is favourable for improving detection efficiency for the super capacitor, the tightness detection requirements of the super capacitor can be satisfied, the whole production efficiency of the super capacitor is improved so as to lower production cost, and the leak detection device has a significant production practice meaning.

Description

technical field [0001] The invention relates to the technical field of supercapacitors, in particular to a leak detection device for supercapacitors. Background technique [0002] Supercapacitor (also called electrochemical capacitor) is a new type of charge storage element. Compared with ordinary batteries, it has the advantages of large capacity, support for large current charge and discharge, long cycle life, environmental protection and pollution-free, etc., and can provide rapid energy release. , to meet high power requirements, so supercapacitors have broad application prospects in new energy, transportation, industry and other fields, and are suitable for electric vehicles, wind power generation and other fields. [0003] However, for supercapacitors, it has some special technical requirements. Among them, the sealing of capacitors is a key technical requirement, which is directly related to the safety and function of the product. Compared with batteries, the sealing...
