This is from the same lab that has the 'breakthrough' battery technologies over the past 20 years :)

  They've been delivering on that reasonably well I think. https://news.mit.edu/2021/lithium-ion-battery-costs-0323 https://news.mit.edu/2021/lithium-ion-battery-costs-0323

    You can find the same curve for most per unit costs when manufacturing scales. No one is doubting decreasing average costs, but similarly no one considers that a breakthrough. A breakthrough is something like an 10x energy/weight ratio, which really does require new chemistry rather than economies of scale or marginal improvements in weight savings that come from more efficient cooling or lighter housing systems. So the solid state batteries that are being developed now would be an example of a true breakthrough. Cheaper batteries in response to a surge in market demand are not.
