Minimizing thickness, maximizing precision

As CCS designs move from bulky plastic trays to using advanced lamination approaches, battery makers can reduce costs, create thinner CCS, and maintain close tolerances for accommodating larger battery packs.

Choice of hot or cold lamination

ENNOVI’s extensive research on adhesives, foils, and processes enables the tailoring of the best choices for each project.

Faster development time

Our proven technology, vertically integrated production, and precision processes lower costs, simplify logistics, and reduce development time.

End-to-end partnering

Instead of starting from scratch with each new design, our proven best practices and core technologies provide a head start on fast time-to-market.

Tailoring the right processes for every project

Our investment in building a comprehensive database of pre-tested foils and methods provides a significant advantage for our customers, from the design inception stage through to full production. Starting with thoroughly tested alternatives helps avoid dead ends and restarts throughout the development cycle.

Product applications

Hot lamination applies both heat and pressure to cure and set the adhesive layer, whereas cold lamination only uses pressure.

While hot lamination is more costly, involves more production steps, and requires longer cycle times than cold lamination, the ultimate test is the quality and robustness of the end-product for specific applications.

ENNOVI offers all three approaches, plastic trays, as well as hot and cold lamination to serve the diverse needs of our customers in the EV and battery manufacturing sectors.
