Submission + - Fast-Charging EV Batteries With Nickel Foil (ieee.org)
gunner2028 writes: Standard electric-vehicle batteries can recharge much of their range in just 10 minutes by including a thin sheet of nickel inside them, a new study finds. This could provide a welcome and economically attractive alternative to expensive EVs that carry massive and massively expensive battery packs. In the new study, researchers experimented with a lithium-ion battery with a roughly 560-kilometer range when fully charged. (The battery's energy density was 265 watt-hours-per-kilogram.) By adding an ultra-thin nickel foil to its interior, they could recharge it to 70 percent in 11 minutes for a roughly 400-km range, and 75 percent in 12 minutes for a roughly 440-km range.
