Problems solved by technology

However, in the existing test device, the structure used to install the diaphragm is fixed in the test box, which is difficult to disassemble, which is not conducive to the disassembly work, and the flexibility of use is relatively poor, and the height of the structure for installing the diaphragm cannot be adjusted, so there are some problems in use. In the existing test device, the relative stability cannot be guaranteed after the protective cover is opened, and it is easy to drop and close, which will affect the installation or disassembly of the diaphragm by the staff, and the effect is mediocre.

Description

technical field [0001] The invention relates to the technical field of voltage breakdown test, in particular to a breakdown voltage test device for a lithium ion battery diaphragm. Background technique [0002] A lithium-ion battery is a secondary battery (rechargeable battery) that mainly relies on the movement of lithium ions between the positive and negative electrodes to work. In the structure of a lithium-ion battery, a battery separator is arranged between the positive electrode and the negative electrode. The battery separator is one of the key inner-layer components. Its main function is to separate the positive and negative electrodes of the battery to prevent short circuit due to contact between the two electrodes. In the general battery processing process, due to the high requirements for the battery separator, after the battery cell assembly process is completed, the battery separator will be tested under high pressure in order to select unqualified battery separ...
