If you read the release they are not positioning the battery as a rival to Lithium ion.
Yeah I think the Guardian has a weird angle on this. Still intetesting tech though.
The news outlets do this with every experimental battery tech. Personally, I probably won’t even know when something effectively surpasses Li-ion for consumer applications until it actually hits the market, since I’ve been conditioned to ignore the headlines.
