The LION seems to have three battery chemistries it uses, (LTO), (LFP) and NCM. The NCM would be the most energy dense, but is also the most likely to fail into thermal run away. (LFP) has a better chemistry that does not easily fail into thermal run away and one would almost have to put a torch to (LTO) for the battery to ignite. The LTO would be the longest lasting battery chemistry in a V2X set up, but again the LTO battery is not as energy dense as LFP that could also work well for V2X systems operations. It will be interesting to see what the long term effects of using the battery pack as a “fuel tank” for a BEV school bus and as a participant in grid services when the vehicle isn’t picking up or delivering students to school.
