Safety in Battery Production Due to Long-Term Tests New Dry-Cleanroom Certificates for igus e-chains

GENTING LANE, Singapore - May 21, 2025 - PRLog -- igus partnered with Fraunhofer IPA to test the long-term performance of its e-chains in dry cleanrooms. The positive results led to new certifications for E6, e-skin flat, e-skin soft, and easy chain E14.

Semiconductor and battery production demand ultra-clean environments, combining dry rooms and cleanrooms. Many components fail quickly under these conditions due to brittleness and particle emissions. To address this, igus tested its e-chains—like e-skin soft, e-skin flat, and E6—in dry cleanrooms. In collaboration with Fraunhofer IPA, they developed new certificates confirming these e-chains' durability and cleanliness in environments with less than 1% humidity.

High degree of cleanliness over 10 months and 15 million double strokes
The two new certificates are divided into "Pre-aging" and "Aging behaviour". For the "Aging behaviour" certificate, two of the energy supply systems, E6.J and the e-skin flat system, were tested in the dry room over a period of 10 months. In the process, they completed over 15 million double strokes. The systems were tested and certified for their ISO class every two months. The e-skin flat survived the double strokes without problems and received the best possible certification of ISO Class 4. A higher certification is not possible because the test environment (ISO Class 3 dry cleanroom with a relative humidity of less than 1%, corresponding to a dew point of -40°C) does not allow for this. The E6.J was also able to maintain this result for four months, but ended up with ISO Class 5, which is a very good result for battery production.

The "Pre-aging" certificate, which was commissioned for the e-skin soft and easy chain E14 energy supply systems, certifies the systems after 15 million double strokes and 10 months in the dry room. Here too, the igus e-chains received the best possible ISO Class 4 certification. Thanks to these long-term studies and certifications from the Fraunhofer IPA, igus was able to confirm that the energy supply systems have very low particle emissions and are therefore safe for automation in the dry cleanroom.
