alt Hacker NewsSaw this yesterday, did not expect the competition around Donut's batteries to heat up this much and this quickly.
Even the gravimetric density is fairly close, CATL's claim is 350 Wh/kg, compared to Donut's 400 Wh/kg.
The safety and durability (plus no lithium) prospects of Donut's V1 battery are still big though (if the thing is actually real).
Feels quite clear Donut doesn't have much - no meaningful new tests released for many weeks already and some executive of Nordic Nano sued Donut Lab and said their claims were misleading.
I haven't really followed that closely myself, but I've noticed the people who I saw defending Donut before have gone really quiet about it lately.
