There’s a lot to be said for lithium-iron-phosphate batteries. They don’t have a thermal runaway problem and will survive the “nail test”. Energy density per unit weight is lower, though. Energy density per unit volume is about the same, but the batteries are heavier.

Lower-end electric cars, such as the Tesla low-end models and most of BYD’s output, have already gone to lithium-iron phosphate. Probably a good idea.
