The Guardian is one of those sources from whom I have come to expect fairly solid reporting. This is a fluff piece with zero information. There is no explanation of what this 'holy grail' of battery storage is, how it works, what it has achieved, etc. I read through the article twice, thinking I'd somehow read too fast and missed the story. It's nothing more than far too many words surrounding some quotes from ARPA-e heads that provide nothing of substance.
