New capacities for larger volume battery cell supply

“As the lead for our Japanese partnerships at Chem4Batteries, finding a reliable, high-quality manufacturing partner outside of China has been one of my key missions. After a long search, I’m proud to say: we signed exactly what we were looking for.

Here’s why this is a big step forward for what Chem4Batteries can offer.

Our core has always been developing custom battery cell formulations from scratch, building lab-based battery cell prototypes to exact customer performance requirements, and engineering complete demo packs around them. That’s where we shine — and we’re not changing that.

But every ambitious project eventually hits the same wall: moving beyond the lab into hundreds or thousands of cells. That scale-up is hard. Sourcing it reliably outside of China has been even harder.

Until now.

With our newly signed Japanese partnership, we’ve closed that gap in the most natural way possible:

C4B: cell formulation development → cell prototypes → demo battery packs
Japan partner: scale-up manufacturing → series supply up to thousands of cells
China partner: scale-up manufacturing → series supply up to millions of cells

Two world-class manufacturing partners. One trusted entry point via Chem4Batteries.

From first chemistry concept all the way to thousands of validated cells and complete battery packs — no handover friction, no supply uncertainty, no compromise on quality.

Working on a demanding project that needs this kind of end-to-end support? I’d love to hear about it. Send me a direct message.”
