No, never. Current charging rates already get close to thermal constraints. Hitting those charging rates either requires accepting much lower power density or using way more metal per cell. This research might inform design changes to improve charging rates, but we’ll never see high capacity batteries charging in a minute.
The researchers know this and only mention wearables and iot devices applications. The article author erroneously makes the leap to high power density devices.
If you don’t care about power density at all, ceramic capacitors can already charge and discharge in microseconds.

It sounds like this is completely clickbait article, bordering on misinformation.

Well this discovery is about super capacitors and not batteries.
