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
