The cost of lithium in the batteries is such a minor expense, that changes in lithium prices cannot move the price of a battery in either direction. The batteries are getting cheaper because of reasons unrelated to lithium, and even if the price of lithium were to quadruple from present levels, these other factors would totally dominate the price of the battery. If something is currently 1% of a price of a good, and it quadruples in price, it can at worst cause a 3% move up in the price of the good. If, at the same time, a different reason causes the price of the good to fall 40%, this 3% move up hardly registers.
