Current battery tech is not scalable, goodbye lithium?

Right now, 45 per cent of global cobalt supply is consumed by lithium-ion battery production, and if lithium battery use doubles or triples as is expected, cobalt supply will be easily overwhelmed.

“It’s not scalable,” said Gerbrand Ceder of Berkeley Labs’ Materials Sciences Division. “If we’re ever to all drive electric vehicles, there’s no way a cobalt-only technology can make it.”

And from Toyohashi University of Technology in Japan, researchers published a report suggesting that calcium ion batteries could theoretically replace lithium altogether.
