A group of Korean scientists, working at the Ulsan National Institute of Science and Technology (UNIST), have developed a fast-charge lithium-ion battery that can be recharged 30 to 120 times faster than conventional li-ion batteries. The team believes it can build a battery pack for electric vehicles that can be fully charged in less than a minute. One of the main issues with rechargeable batteries is that they take longer to recharge as their physical volume grows. When you recharge a battery, it charges from the outside in — so the fatter the battery, the longer it takes. You can somewhat avoid this by breaking larger batteries into smaller individual cells, but that technique only gets you so far.
