The report says researchers placed battery ingredients in a solution containing graphite which was later carbonised “to form a dense network of conductors throughout the electrodes of the battery”.
This means that the energy-holding particles of the battery begin re-charging at the same time. With traditional batteries these particles apparently only charge from the outside-in.
The end result of all of this particulate boffinry is that the resulting batteries can be recharged in anything between 1/30 and 1/120 of the time taken to re-energise conventional rechargeable batteries.
I wonder if the charge would not be more energy efficient too. I seem to recall that conventional batteries have a "back force" that makes it harder to add more charge the more you have. If so this might bypass that.

Interesting but will they be able to be made strong enough for vehicular use? Cars in the real world take some pretty heavy jolts.
