  1. The price for battery chart is very inaccurate. The price for 18650 cells are down maybe 30% in the last 7 or so years, not the crazy number in the chart. The price in the chart is probably including manufacturers subsidizing EVs, that money came from either outside investors or lenders such as with Tesla or internal investments from established car makers so it is artificially cheaper. The real price to follow is that of the 18650 or 21700 cell and that is where the price change is much more realistic and tame. Also to note that batteries such as 21700 and 18650 have the same exact power to mass ratio just that one is slightly bigger and so it has an equal increase in capacity but technologically and chemically they are the same, just a different size to better fit one car or another. Maybe an SUV can squeeze in a few more 18650s or a flat battery in a small sedan like the Model 3 can fit more in with 21700 but they are overall the same battery chemistry just different sizes.
