Not so easy to eliminate cobalt.

No easy task to cut cobalt from batteries“Tesla has been talking about it for a long time, so it is somewhat unsurprising,” Caspar Rawles of Benchmark Mineral Intelligence told the Investing News Network (INN). “To remove cobalt is extremely challenging from a technical standpoint, and I believe the technology is still being developed by Tesla.”The EV maker is on a quest to remove cobalt and increase nickel, which would bring more energy density to its batteries. But more nickel at the expense of cobalt means lower cathode stability, Gavin Montgomery of Wood Mackenzie further explained.“To get around this, ‘novel coating and dopants’ were mentioned,” he told INN. “However, without further details, we are not convinced the problem has been solved just yet.” QUOTE.
A lot of talk but cobalt is imperative for stability in EV batteries IMO
