A new lithium battery technology might mean rapid charging and discharging times that take just seconds instead of the minutes or hours we're used to.
Years ago, scientists thought that the reason why lithium-ion batteries have slow charging and discharging times is because the ions travel across the battery slowly. But that wasn't the case at all; in fact, various tests reveal that the ions are shuttled across the battery very quickly.
The real reason why charging and discharging times are slow, is that the ions can only travel through tunnels accessed from the surface. Only ions positioned immediately at the entrance of the tunnels can be shuttled across. The answer then to the slow charge/discharge cycle is to design a new surface more conducive to traveling.
