Future Cameras May Have Lithium-Ion Batteries That Recharge in Minutes

What if the battery in your camera could be charged in the same amount of time it takes to microwave a cup of instant noodles? It sounds crazy, but that’s what appears to be headed our way.

Researchers at the Ulsan National Institute of Science and Technology in South Korea have figured out a way to drastically cut down the time it takes to recharge a lithium-ion battery — the same kind found in most digital cameras.

The major breakthrough has to do with how the batteries are built. Li-ion batteries currently on the market charge from the outside in. Only at the end of the charging process is the center portion of the battery filled with charge. Think of it as an uber-dense cotton ball dropped into a liquid solution.
