> Iron fluorides have more than double lithium’s capacity of traditional cobalt- or nickel-based cathodes. In addition, iron is 1/300th the cost of cobalt and 1/150th the cost of nickel.

I'm curious how much the cost of cobalt/nickel is relative to the whole battery's cost.

The lowered geopolitical risks and general availability could be significant regardless.

Some information about battery parts cost: https://about.bnef.com/blog/behind-scenes-take-lithium-ion-b...

Lithium itself is ~79%, Both Nickel and Cobalt are less than 4/5% each.

What do you mean here? Lithium is a tiny portion of a li-ion cell, about 1g in an 3600mAh 18650 cell. There is significantly more of Nickel, Manganese, and Cobalt in an NMC cell for example.

Perhaps he means 79% of the cost, rather than 79% by mass or volume.

He'd still be very wrong. Cathode materials are less than 25% of the typical cell price.

This comment is meaningless without clarifying

- which chemistry is being discussed

- what these percentages represent: weight, volume, or cost

There is no lithium-ion battery (NMC/NCA) where Li corresponds to 79% of any of those.
