  That graph is a bit deceptive; the X axis is not linear, but instead shows years 2008, 2010, 2013, 2017 and 2020.

    It's wrong anyway. Even back in 2008, it was more than 50 watt hours per liter. The graph is taken straight from the DOE website, here: https://www.energy.gov/eere/vehicles/articles/fotw-1234-april-18-2022-volumetric-energy-density-lithium-ion-batteries#:~:text=In%202008%2C%20lithium%2Dion%20batteries,450%20watt%2Dhours%20per%20liter https://www.energy.gov/eere/vehicles/articles/fotw-1234-apri.... Without attribution of course. They just re cited the paper the DOE cites. The paper has no such graph: https://www.osti.gov/pages/servlets/purl/1842609 https://www.osti.gov/pages/servlets/purl/1842609 The graph is clearly wrong.

  That graph is plainly wrong. The initial point is at the same level as a lead-acid battery. There is no chance it is legit.

    They wouldn't know since they stole it from the DOE website here: https://www.energy.gov/eere/vehicles/articles/fotw-1234-april-18-2022-volumetric-energy-density-lithium-ion-batteries#:~:text=In%202008%2C%20lithium%2Dion%20batteries,450%20watt%2Dhours%20per%20liter https://www.energy.gov/eere/vehicles/articles/fotw-1234-apri.... (The cited paper does not contain this graph, see https://www.osti.gov/pages/servlets/purl/1842609 https://www.osti.gov/pages/servlets/purl/1842609)

      That graph must be a misunderstanding by the DOE then.
