In five to 10 years, ultra fast-charging EV batteries might be possible, but there are still science and engineering challenges to overcome before they are both technically feasible and affordable
In a solid state design, lithium metal batteries should in theory be able to charge up very quickly. In practice, though, they too are prone to forming dendrites, causing them to fail quickly, especially at high charge speeds. Fast-charging lithium metal batteries would be the Holy Grail of high performance EVs batteries, but they are “still a work in progress,” Buettner-Garrett says.
several different layers of materials in the electrode to arrest lithium dendrite growth. In the journalthat could be charged in just three minutes, while retaining more than 80 percent of its capacity after 10,000 cycles. Li says that a commercial version of this battery may be possible in about five years “if everything goes right.”
“There is another layer of consideration on the infrastructure,” Li says. “We have to see how much current the entire system can support.”
