When lithium ions are forced rapidly through a battery, they might get stuck and turn into lithium metal, no longer able to move through the battery, says TechXplore.
Imagine being able to refuel your electric car while stopping for a quick snack or refill your phone while brushing your teeth.
“Fast charging is kind of the Holy Grail. It is what everyone who owns a lithium ion battery based device wants to be able to do,” says Senior Engineer David Wragg from Centre for Materials Science and Nanotechnology at the University of Oslo.
Inside the battery, however, there is a lot of complicated chemistry that can be sensitive…
