the Lithium ion battery uses Cobalt in the reaction.
See below for the chemistry. That is why I have FCO. Yes there will be better batteries down the road but for now.....

Lithium companies seemed to have been in a bit of a bubble 6-8 months ago so I stayed away trying to determine which were real.
