The Donut battery a nothingburger or the holy grail?
In march/april the chemistry behind it can be validated or aborted when they will market a motorcycle that runs on the donut.

4. Conclusions and summary

This project included independent charging performance tests on the energy storage devices supplied by the customer, which the customer identified as solid-state battery cells. Based on the initial capacity test, the nominal capacity was determined to be 26 Ah. The cell was charged at 5C (130 A) and 11C (286 A) in acc rdance wit t e c st er’s test plan, and capacity, ener y, cell temperature, and charging times were recorded.

Under the specified test conditions, the cell was successfully charged at 5C for more than 9 minutes, and 100 % of the charged capacity was available during the subsequent discharge. The cell was also successfully charged at 11C for more than 3 minutes, with 98.4–99.6 % of the charged capacity available after a full charge.

I'll believe it when it shows up powering brand name EVs.

Solid-state batteries are the current [pun intended] Holy Grail of battery manufacturers, so it's a field ripe for con artists to pick suckers, pardon me, investors pockets.

Indeed. All the more curious why the didn't donut people would on purpose risk being exposed as lying fakers.
