How it works

  1. Dielectric layer
  2. Frame
  3. Traces
  4. Current collector

Simplify CCS complexity

Designing pouch CCS presents several challenges, primarily due to the need to balance cost, performance, and mechanical requirements. EV and battery makers are constantly seeking new innovations that can maintain or improve performance while lowering costs, and provide reliable mechanical support for the battery cells, all while addressing safety and longevity concerns.

Advanced lamination technology

ENNOVI-CellConnect-Pouch utilizes ENNOVI’s proven lamination technology, which ensures structural integrity and durability. Low-voltage signals are added on one side of the lamination, thereby reducing material used and resulting in a thinner solution.

Supports fast gas release

Pre-cut material with good electrical insulation properties and temperature stability, featuring optional gas vent cutouts.

Cost-efficient

Our proven technology, combined with knowledge in CCS, vertically integrated production, and precision processes, helps lower costs, simplify logistics, and reduce development time.

Thinner, lighter, and tougher

Moving away from conventional CCS designs that use bulky plastic trays, ENNOVI-CellConnect-Pouch utilizes advanced lamination technology to create thin and lightweight solutions that enhance electrical and thermal performance at a lower manufacturing cost. ENNOVI’s FDC is integrated at one end of the lamination, eliminating the need for two layers of insulation material.
