Why is there never a single relevant metric mentioned? Here its only cycles and efficiency (which I assume is capacity).
This article is just blogspam reporting of an SCMP article, which also doesn't link to the paper, which is here: https://advanced.onlinelibrary.wiley.com/doi/10.1002/aenm.202506734
But the full text is not available there. You might be able to find it elsewhere.
Now, is that cause for worry or am I silly?
I don't think China does April Fools' Day.
Scientists generally don't do it.
