Thanks, woops yes, i have been saying "HEV" when i meant "Hydrogen FCEV".
IMHO, having a total reliance on Lithium, which may only be available in a few places which may get bought up by a single country/company, seems a bit dodgy.
Also, Fuel cells seem easier to reclaim platinum from, than reclaiming lithium from big car batteries, where each cell is welded in.
IMHO, reclaiming lithium from a big dead car battery sounds more difficult than actually extracting lithium from "Lithium ore".
And 5 years down the line from now, how many BEV owners are going to be bringing their BEV in to the garage and saying, "ive got a rogue cell just come up, and my battery capacity is down by 40%" ?
..We wont know till 5 years time.
Also, IMHO, i reckon its easier to heat up a small fuel cell for -10degC operation, than heating up a big BEV car battery?
