Yep, but, big, big but: you can make bigger cells out of it. 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.
