Why are we not already able to “instant-charge” EVs, smartphones or other batteries?
In: Physics
The best analogy I’ve seen is that a battery is like a car park. To charge it, you have to park all the lithium ions on an electrode, but there are only so many spaces for the ions to fit. Just like when a car park is busy, it can take the ions some time to find a space, and it gets more difficult the closer you get to fully charged.
