My EV with cobalt in the batteries seemed practical to me.

And nothing wrong with having some lithium in their battery. The important thing is how much cheaper is it.

Your EV probably has the usual NMC or NCA chemistries which have around 10-20% cobalt. I don't know of any car that uses a 100% LiCoO2 cathode — it's just not practical.

Cobalt is practical if you want to make low millions of cars. It ceases to be practical if you want to make a billion cars. There just isn't enough of it readily available to scale.
