“The Chinese manufacturing giant CATL, the biggest supplier of batteries for the world’s electric cars, said on Monday that it had made technological advances..
The biggest surprise by CATL was an announcement about auxiliary batteries for electric cars. The batteries would share space in the underbody of cars, where there is now only one large battery.
The auxiliary battery would be the first commercially available electric vehicle battery that would not use graphite as one of its poles, CATL said.
Removing costly graphite will eventually make the batteries cheaper, after some initial costs, and will allow 60 percent more electricity to be squeezed in each cubic inch of the battery…
CATL … also said it had made more progress in the speed of charging main batteries. The company said its new system would allow an electric vehicle to be charged enough in five minutes to drive 520 kilometers, or 320 miles.”
