From what I understand, lithium iron is actually less power dense than the latest lithium ion, but it can handle more charge cycles and it’s less volatile nature allows manufacturers to break away from the commoditized cells paradigm. It’s not considered a good choice for eg ebikes because of the density issue.

In comparison Tesla S carries huge amount of dead weight in 18650 casings, redundant conductors, electrodes, and battery module casings. BYD Han has very big cells, and single simple module body, and actually beats Tesla on whole battery energy density. Try to do it with cobalt base cathodes, they will shred themselves with internal expansion after a few charge cycles.
