The study shows that the buildup on battery electrodes is a side effect, not the root cause, of performance loss.

Sloman Rating: "on-topic" - science, 0

It's not major news - nobody has used it to make better batteries yet, and while the inventors are hopeful that it might be exploited to do that, it may just be a much of an irrelevant distraction as the interest in dendritic lithium deposits was before it.

It is science - rather than electronicis - so less "on-topic" and helpful rather than useful, so +1.

The whole point of the paper was to boast about a technique that finally let them do it.

Of course they are, but nobody has used it to improve the solid electrolyte interphase layer yet.
