Why polycarbonate-based packaging?
For electric vehicle battery packaging, no other engineering thermoplastic can bring what polycarbonates offer:
- A proven track record of performance. Polycarbonates are already the material most commonly used in packaging Li-ion cells whether for electronics or electric vehicles.
- Unmatched versatility when compared to other engineering plastics. Achieving high energy density requires a packaging material that is tough, easy-to-process and ultimately able to unify tasks and reduce component count.
- Most competitive value. With a large installed global production capacity your application can grow uninterrupted at the lowest possible cost and still benefit from formulation improvements and optimization.
Smart packaging starts with the right materials
To design the best battery packs, engineers need to balance the need to maximize energy density while keeping cells safe and cool. The right materials allow the best designs to emerge. And no other material offers the versatility polycarbonates have to offer. From cooling devices to pack enclosures, Covestro is ready to support your product development efforts with the right formulations and advanced applications development expertise.
New thermally conductive polycarbonates allow the design of innovative cooling plates that are partially or fully plastic. Such designs enable integration of complexity and components.
What if you could integrate water-glycol cooling channels into cell holders? new conductive and hydrolyses-stable polycarbonates allow such designs.
Flooding and cooling an entire battery module with a dielectric fluid can be achieved with a hermetically-sealed laser-welded polycarbonate enclosure.
Prismatic Cell Covers
Flame retardant PC/ABS formulations offer the best value for prismatic battery cell covers for prismatic cells.
Pouch Cell Frames
Frames that provide structural support can be made of flame retardant PC/ABS or even thermally conductive formulations for mechanical integrity and heat management.
Cylindrical Cell Holders
Bayblend FR3040 offers the best processability for the thin walls required in cylindrical cell holders. New formulations can also improve thermal management.
Large part manufacturing is now possible with specially formulated FR PC/ABS that completely bypass the issues normally faced in top covers made of semi-crystalline resins and thermosets.
Covestro polyurethane and composite manufacturing technology is available as a new and exciting alternative to metal underbody structures.
To avoid vehicle side-impact and battery damage, leading OEMs are already using Covestro PC-blends which maintain their toughness over a wide range of temperatures.
Many e-mobility applications for light electric and utility vehicles required modular and exposed battery housings that need to be tough, versatile and UV-stable.
