Robust adhesive-free, heatless lamination

The cost of cold lamination is low, but the robustness and performance of hot lamination is better. Using our knowledge in laser welding, lamination and cell contacting system design, we innovated our Adhesive-Free Lamination Technology to eliminate trade-offs, while delivering both low cost and robustness.

Reduces cost & development time

Compared to hot lamination, ENNOVI’s Adhesive-Free Lamination Technology is 50% lower in insulation material cost and provides up to 80% faster processing time due to its materials and streamlined processes.

High design flexibility

Supports a wide range of designs for various battery form factors – including prismatic, cylindrical and pouch battery cells.

Saves energy & conserves resources

Uses less than 5% energy as compared to the conventional hot lamination process. The absence of adhesive avoids its respective environmental impact.

High efficiency, low impact to the environment

Proven to be as robust and durable as conventional hot lamination, but with 50% lower cost, 80% reduced cycle time and 25% space savings. This patent-pending technology does not degrade the material properties as can occur with hot lamination and reduces the impact to the environment.

How it works

  1. Lamination Layer
  2. Adhesive-Free Lamination(signal)
  3. Current Collector
  4. Low Voltage Harness

Applications

ENNOVI’s Adhesive-Free Lamination Technology positions the current collector between 2 foils and joins the top foil to the bottom foil. The foils get sealed around the current collector, forming a tight pocket to secure the current collector and providing insulation between each current collector. This proprietary innovation is ideal for diverse designs and well suited for large assemblies in various battery form factors.
