E-mobility technology supplier ENNOVI has introduced an adhesive-free lamination technology designed to achieve stronger, more sustainable cell contacting system (CCS) assemblies for various battery cell form factors, including prismatic, cylindrical and pouch.

ENNOVI’s technology positions the current collectors within the CCS between two insulation material foils and bonds them with a specialized joining process without the need for adhesive. This process creates a tight pocket around the current collector to secure its position for enhanced structural integrity and provides appropriate insulation between each other to enhance the battery’s lifespan.

The new process halves the insulation material cost, consumes less than 5% process energy and accelerates processing time by 80%, compared to conventional hot lamination, providing enhanced flexibility and manufacturing efficiency to global OEMs and Tier 1 suppliers, according to the company.

“Cold lamination presents the battery manufacturing industry significant savings in processing time and energy consumption during CCS assembly. Hot lamination, on the other hand, has other benefits such as robustness,” said Till Wagner, Product Manager for Energy Systems at ENNOVI. “Using our knowledge in joining technologies and CCS design, we innovated our adhesive-free lamination technology to eliminate trade-offs, while delivering both manufacturing efficiency and robustness. Moreover, this new process does not degrade the properties of the insulation material.”
