Coming to a car dealership near you in 2177. Battery breakthroughs have been happening bi-weekly for decades

• Maken 2y ago
  Batteries are not like fusion energy, we have actually seen continuous improvements in the last 40 years.

  They hit way sooner than you think. The current best in class battery cells are a hybrid of these breakthroughs. Companies just don't advertise what's going into the special sauce for obvious reasons. If you look at a chart if battery capacity density, it's been pretty much exponentially growing.

    Do you have such a chart handy? The last one I checked showed a linear 10% / year increase, something like that...
    • chopin 2y ago
      A 10% increase per year is exponential.
      • illiac786 2y ago
        yes, ok, but it’s far from e. Let’s say “exponential” is a shitty term, it can mean very different things. But 10%/y is still a doubling within 8 years, so maybe not so bad – if my memory is correct. [edit] see other comment, it is indeed very much linear, not exponential at all.

      There is a chart here: https://www.researchgate.net/figure/Advances-in-energy-density-of-selected-battery-types-by-year_fig2_294580055 https://www.researchgate.net/figure/Advances-in-energy-densi... I am a bit confused by the units but it seems to be growing, tho the data cuts off at 2005. Another chart is here: https://physicsworld.com/a/lithium-ion-batteries-break-energy-density-record/ https://physicsworld.com/a/lithium-ion-batteries-break-energ..., still does not seem exponential, looks kind of of linear to me.
      • illiac786 2y ago
        the first one shows linear progression, not even 10%, except the prototypes at the end. Second one shows a linear progression too it seems, I agree.

  There are consumer products shipping with solid state batteries.

  >Battery breakthroughs have been happening bi-weekly for decades and our batteries now compared to then (ten years ago, twenty years ago, thirty years ago) are amazing. It's one of the few technologies where we actually have seen leaps and bounds of improvements and overall quick dissemination of technologies to the public.
