I am assuming the article meant "...a phone battery that can be charged in one minute..."
Quite, although the scientists have not invented a mobile phone battery.
They have invented battery technology which, if used in an application the size of a mobile phone battery, could be charged in one minute.
Presumably an ebike sized battery would take a lot longer charge, albeit it would be much quicker than current ones.
Or maybe not, perhaps any size of battery using this technology would charge in a minute, if you had enough grunt to put into it.
Good thing I'm not in charge (ho-ho) of battery development, we'd still be using Voltaic piles.
