ENNOVI Secures German Patent Approval for Adhesive-Free Lamination in Battery Cell Contacting Systems

Offering a new, validated CCS design pathway, reducing uncertainty for cautious battery engineers

NECKARSULM, Germany, March 25, 2026 /PRNewswire/ -- ENNOVI, a global leader in e-mobility interconnects and an engineering partner to the automotive industry, today announced the approval of a German patent for its innovative adhesive-free lamination technology for battery cell contacting systems (CCS). The laser lamination technology eliminates the need for adhesive used in conventional hot and cold lamination processes, enabling battery designers to develop a more sustainable CCS, faster.

"The patented intellectual property (IP) underscores ENNOVI's continued research investment in advancing battery CCS technology," says Randy Tan, Product Portfolio Director for Energy Systems, ENNOVI. "Automotive OEMs and battery manufacturers can design in the unique features of adhesive-free lamination, reduce engineering risk by using a technology that is already validated, rather than reinventing it."

The continuous introduction of such innovations enables ENNOVI to help OEMs overcome the economic and technological pressures of global competition. Patented technologies provide a safe, fast, and cost-effective route to delivering high-performance automotive solutions. OEMs benefit from pre-validation and the connected reduced risk, lower overall costs, and accelerated development timelines. ENNOVI supports flexible engagement models, including co-development and tailored engineering support, ensuring that partners maintain control over their product roadmaps and technical decisions.

This latest patent confirms ENNOVI's strategy to provide high added value and specialized expertise in complex solutions. The company's extensive technical CCS design offering, which includes hot and cold lamination as well as its adhesive-free lamination, ensures that engineers have a 'menu of selection' for their chosen battery architecture, whether cylindrical, prismatic, or soft pouch cells.

ENNOVI's Advanced Solutions Engineering Center in Neckarsulm, with prototyping and testing capabilities and an R&D laboratory, plays a key role in accelerating product development. This local proximity, coupled with ISO 9001:2015 and TISAX certifications, enables engineers to collaborate closely and ensures compliance with demanding quality standards and automotive supply chain data protection requirements.
