The winding system, which also features an inline quality check, enables the automated and digitized manufacture of jelly rolls in different designs and formats. (Photo credit: Fraunhofer IPA / photo: Rainer Bez) For contacting with welded current collectors, a robot places the tabs on the anode and cathode, which are then joined together using ultrasonic welding. (Photo credit: Fraunhofer IPA / photo: Rainer Bez) The notching of the anode and cathode is performed with an integrated laser cutting system. The various contact options can be combined as desired. (Image source: Fraunhofer IPA / Photo: Rainer Bez) The buffer ensures that sufficient cathode and anode material is always supplied to the continuous winding process. (Image source: Fraunhofer IPA/Photo: Rainer Bez) The quality of the windings is checked in the system by means of a hi-pot test. The dimensional accuracy regarding winding geometry and current collector position is verified through optical inline inspection. N.i.O. cells are automatically sorted out.

E6, e-skin flat, e-skin soft, and easy chain E14 demonstrate their suitability for the dry-clean room in the long-term test conducted by Fraunhofer IPA

Safety in battery manufacturing through long-term testing: Innovative dry cleanroom certificates for igus e-chains

Already two years ago, igus presented the E6.29, the first certified energy chain for the dry cleanroom. To provide its customers with long-term security, the motion plastics specialist commissioned the Fraunhofer IPA to conduct a test to investigate the aging behavior of its e-chains in the dry cle…
