" 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.
