Same battery in all HEV(LE/XLE/LTD). PHEV battery different between solar roof or no solar roof. Pretty sure all three are Li. (like 99% sure)
They are all Li-ion in the gen5. At least for North America. For the past hybrids, the different batteries were designed to be swappable in manufacturing. So other markets could get NiMH. Toyota even had Li-ion in a past Rav4 hybrid for a half year here from a presumed NiMH shortage.
