Abstract

The invention discloses a device for detecting the durability of a lithium ion battery cell. The device comprising an air cylinder, a battery cell groove used for loading a battery cell, a loading mechanism used for loading the battery cell groove, a corrosion mechanism used for carrying out corrosion operation on a battery cell cover plate in the battery cell groove, an inversion mechanism used for inverting the corroded battery cell and a mechanism used for checking the inverted liquid injection port battery cell, and the output end of the air cylinder is fixedly connected with the battery cell groove; the air cylinder drives the battery cell grooves in the loading mechanism to sequentially pass through the corrosion mechanism, the inversion mechanism and the inspection mechanism; and by adopting the device for detecting the durability of the lithium ion battery cell, the durability of the sealing opening of the battery cell is quickly and effectively judged, the performance of the battery cell is improved, and the liquid leakage phenomenon of the battery cell put into the market for use is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of lithium battery preparation, in particular to a device for detecting the durability of lithium ion batteries. Background technique [0002] In recent years, the development speed of the new energy industry is getting faster and faster. Due to its environmentally friendly green characteristics, lithium-ion batteries are more and more widely used in the 3C market, the electric vehicle market, and the energy storage market. With the decline of the national subsidy policy, in addition to cost advantages to win the favor of the market, it is also necessary to achieve a longer shelf life in terms of cell performance to meet customer requirements for vehicle life. [0003] As for how to improve the performance and shelf life of the battery cells, various manufacturers use various methods such as battery core materials, battery core design, battery core size and model to improve the battery life and various elect...
