@vicariously 1,
"If we're being real, there's no evidence to suggest that a zero cobalt battery could become commercially viable in the next five years."

The following would suggest that Panasonic and Toyota disagree with your above statement. Solid state batteries need no cobalt.

"Panasonic and Toyota among others bet that solid-state batteries will mean all the difference when moving beyond current lithium technology. They are joined in this belief by 23 players in Japan that have formed a consortium. The alliance is led by New Energy and Industrial Technology Development Organization, or NEDO. NEDO previously engaged in solid-state battery research primarily with materials makers.
The research management group of the new consortium set a target date of 2022 for the core technologies to be ready for market."
