Korean carbon-coated lithium-ion battery could cut recharge times down to minutes

South Korean boffins say they have found a way to cut battery charging times for electric cars from hours down to just minutes.

The discovery changes the way materials used in regular batteries are treated, according to a Yonhap report.

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.
