The battery price revolution started way before 2019. There’s nothing unprecedented about today’s battery prices from the PoV of 2019. In fact, your own data says that in fact the price decrease has been slowing down: Besides the visible fast decrease between 2014 and 2017, prices-per-kWh were about $128 in 2018, $120 in 2019, $110 in 2020, $99 in 2021, and then pandemic inflation spiked it and three years later it only managed to decrease to $78 in 2024. No, I don’t think battery prices are falling faster than we expect them to.
