Something about this really stinks...

Update on 28th August 2026: we got the approval to publish the reports in their entirety. In the previous episode we said we would have our bipolar cells verified by a third party, and Intertek has now done it, opening the cells and confirming that these are true bipolar cells. Intertek then drove a nail through a fully charged cell, and nothing happened. No smoke, no fire, no thermal runaway, which makes it one of the most boring videos you will ever watch and exactly the result we wanted.

Density reveal..........

The gravimetric energy density was determined to be 409.3 Wh/kg
The volumetric energy density was determined to be 804.7 Wh/L.

Since the day we announced Donut Battery, no question has come up more often than this one: how much energy does the cell actually hold for its weight? After what may have felt like forever, we put it on a scale. VTT weighed the cell, measured its dimensions, charged it fully, discharged it at room temperature and logged every watt-hour that came out. Watch the video for the result, and download the report if you want to check the full process yourself.

So a reasonable shorthand for 2026: typical commercial Li-ion cells land in the ~160–320 Wh/kg range, with niche cells pushing toward 400–450 Wh/kg, and the practical ceiling for the technology estimated at 400–500 Wh/kg.

Is anyone else on YouTube or mainstream EV news even reporting on Marco's lies anymore?

I watch a lot of different channels related to EVs and I haven't seen anything in a while now.
