A breakthrough in battery technology?

The ExtremeTech website has reported a possible major major (i.e. game changing) breakthrough in Li-Ion battery technology with the headlines:  New lithium-ion battery design that’s 2,000 times more powerful, recharges 1,000 times faster

If this turns out to be technology that can indeed be commercialised, then just imagine the possibilities: (1) electric cars with far lighter batteries, or electric car batteries with much greater range, (2) mobile phones with tiny batteries that can be charged in a minute or so, (3) portable HF transceivers that last for days between charges.
