apparently the problem is there is not yet enough volume in production to compete on price, which I thought was the whole point?
> sodium-ion specs have improved to the point that the technology could break into the general EV market. A recent study by Moritz Schütte at Aachen University in Germany and his colleagues found that a sodium-ion battery by the manufacturer Hina rivals Tesla’s lithium-ion batteries on most parameters, although it would still be a third heavier
> But CATL claims its sodium-ion battery has an energy density of 175 watt-hours per kilogram, which can compete with the lithium-iron-phosphate batteries in low-cost models from Tesla and others. And while sodium-ion batteries still haven’t quite beaten lithium batteries on price, that could change as they expand, according to Schütte
> sodium ions generate less heat in electrochemical reactions, reducing fire risk, so less money can be spent on cooling. They also form weaker bonds with the electrolyte, so they don’t slow down as much in the cold
