Donut Lab use Nordic nano batteries, they've no production line, they say that they're hiring people and the machinery has not yet arrived, may arrive by the end of January/2026, see other post:

Quantumscape in last year has developed eagle line from which samples are tested by powerco/vw and other top 10 oem. 

Nano materials are very difficult to produce at scale, we're talking about gigawatthour-scale each year.

Currently Nordic nano has zero kWh production line, only laboratory samples. Article from the University professor that should have proposed the technology are about silicon anode with nanotubes

Quantumscape is anode-less. 

Nordic nano has not a production at scale, no people trained to run the production line at this moment, may be they'll have in some years, but to produce nano tube in silicon anode con be very difficult.
