" CATL has thrown its hat into the ring with the Naxtra sodium-ion battery, with 175 Wh/kg and 10,000 lifetime cycles along with operation from -40°C to 70°C. CATL is planning a start-stop battery for trucks using the technology. It has the potential to replace lead-acid batteries. CATL has announced battery pricing at the cell level in volume at $19/kWh.

I don't know if the same applies to sodium batteries, early indicators are that they are less sensitive to depth of discharge as a degradation driver.

Still, the expected lifetime is going to be at least between 4-8 times NCM (traditional li-ion), which is massive.

Definitely incredible but I still feel like people’s excitement is misdirected.

  • they’re less energy dense so not likely to be on phones or many cars
  • for cars the extra life is marginal when existing batteries already last more than the life of a typical vehicle
  • much cheaper will make a huge difference in low end cars.
  • but storage is the killer app! I don’t care about energy density but they’re much cheaper and will last much longer. Huge win!

Imagine if home battery systems cost half as much but last four times as long! Or grid storage! This is huge!
