My takeaway is that nanowires like this are applicable both in capacitors and in batteries; they&#x27;ve determined a way to make them much more durable in capacitors and if they can duplicate that within batteries then it&#x27;s going turn out to be an even larger discovery than it already is.<p>If they were actually working on this only for batteries, then presumably capacitors are simply a test methodology that allows them to test hundreds of thousands of cycles within a reasonable time period.
