GM batteryJust caught this via @Brandy on CEO.ca: GMs new Ultium battery system contains 90% nickel with 70% less cobalt. It will power 30 new GM models by 2025, including the hyped GMC Hummer EV and the Cadillac Lyriq.The Ultium battery is expected to get a range of 400 miles per charge sufficient enough to erase almost anyones range anxiety. GM also expects its costs to make electric vehicles to drop by nearly a third from what it spends now making the Chevrolet Bolt.
