" 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.

If I recall well, it isn’t a good fit for cars as it energy density per weight isn’t as good. But for residential batteries, that’s huge (if true).
This isn’t true any more, and it’s mentioned in the article. Sodium is at least equivalent to - and on pace to surpass - the energy density of Lithium. It’s already being used in passenger cars in the Far East.
