    My understanding is that Elon is "all in" on lithium, including the Semi and model P(ickup).

    Li-ion has the cost advantage along with the energy density. NiMH handles cold better, so it might work for niche products; electric snow machines.

    Space? doesn't make a difference since they are both under the seat, though Toyota could put a larger Li-ion there if they chose.

    Sales? don't know; need sales figures broken down by trim.

    sorry, someone mentioned that lithium was more compact than nimh.

    It is, but it doesn't make a difference to the car owner in terms of usable space, because the space under the rear seat isn't usable space. The Li-ion takes up less space there than the NiMH for two reasons. The first is because of higher energy density, and the second is that it requires a smaller amount of buffer capacity, so the overall capacity is smaller.

    If you did make it so you could use the under seat space for storage, then you could put a few more things under there with the Li-ion pack than with the NiMH one. However, this is just a hybrid with a tiny battery. For a plug in, the difference in pack size will be more pronounced, more likely it will be seen in the EV range. When the EV1 went from lead-acid to NiMH, GM didn't limit the NiMH capacity to that of the original battery, they increased it because they could fit more of it into the space occupied by the 12 volts.

    If were to replace a BEV of today's Li-ion battery with NiMH, you would end up with less range, or lose car space for the physically larger battery.
