If we met you at The Battery Show North America, thank you for stopping by. We had some great conversations with cell designers, pack integrators, engineers, and technical leads, all focused on solving the same challenge: how to build batteries that are lighter, faster, and more efficient without compromising performance.
For us at Avocet Battery Materials, the answer starts with one component: the tab. And more specifically, Flyweight, our proprietary bimetallic solution that’s redefining what’s possible with pouch cell tabs.
Why Flyweight?
Flyweight was engineered for sectors where every gram matters: motorsport, aerospace, eVTOL, defence, high-performance EVs. It replaces most of the copper typically used in pouch cell tabs with aluminium, reducing weight by up to 5.63 kg per 1000-cell pack, while still maintaining:
- Copper-to-copper welding at the foil stack
- Aluminium-to-aluminium welding at the module
- Excellent conductivity (no adhesive or weld used in bonding)
- Compatibility with corrosive or high-voltage chemistries
- A tapered edge for full sealing, even in thick (>1 mm) tab designs
Whether you’re designing for range, runtime, or acceleration, the tab is no longer a passive component. With Flyweight, it’s part of the performance equation.
Built for Integration, Not Just Innovation
We understand that innovation means nothing if it doesn’t fit your process. That’s why Flyweight is:
- Fully customisable to your cell or module format
- Scalable – from R&D runs to mass production
- Backed by engineering support for seamless integration
Our tabs are manufactured in the UK, with short lead times and responsive technical collaboration, because we know how fast your programs move.
Let’s Keep the Conversation Going
If we connected at the show, or you’ve just discovered us, we’d love to learn more about your program and how Flyweight can support it.
Flyweight isn’t just another tab. It’s a strategic advantage for high-performance pouch cells.
Let’s turn your concept into a competitive edge.
