Car manufactures are aiming at reducing the amount of cobalt in lithium batteries

Here is an interesting article from Bloomberg for those of you who follow Electrical Vehicle material supply chain and lithium battery technology

Hype Meets Reality as Electric Car Dreams Run Into Metal Crunch

When BMW AG revealed it was designing electric versions of its X3 SUV and Mini, the going rate for 21 kilograms of cobalt—the amount of the metal needed to power typical car batteries—was under $600. Only 16 months later, the price tag is approaching $1,700 and climbing by the day. For carmakers vying to fill their fleets with electric vehicles, the spike has been a rude awakening as to how much their success is riding on the scarce silvery-blue mineral found predominantly in one of the world’s most corrupt and underdeveloped countries.

If each of the billion cars on the road were replaced today with a Tesla Model X, 14 million tonnes of cobalt would be needed—twice global reserves. Even a more realistic scenario for people to drive 30 million electric cars by 2030 requires output to be more than trebled, according to a study commissioned by Glencore from commodity analysts CRU Group.

The Bloomberg article focuses on BMW technology but presumably this game of reducing cobalt is followed by all car manufactures. Especially interesting is the comparison on how much cobalt is in each cathode technology. The article also give a good overview on the supply issues for cobalt.
