The internal corrosion is a very difficult problem in the lithium battery industry, because it is usually hard to find out the corrosion of soft-packed lithium battery triggered by electrochemical reaction. Generally, it could be found only when the lithium battery has been used for a long time. This kind of failure mode has a long latent time, and it is easy to cause potential safety hazard of the battery once it occurs.

Qianhai Jorho's internal corrosion detection equipment can effectively detect the insulation defects of lithium battery ear film and aluminum plastic film PP layer after the electrolyte is injected into the battery.

Operating Method：

①Applying impulse to lithium battery after electrolyte injection

②Monitoring charged energy during test time

③Discharging the remaining

Characteristics:

①High Reliability

②Less damage

③Faster cycle time
