Sodium-ion battery cells are a trending topic, as sodium-ion technology offers some advantages over the established lithium-ion approach. Sodium is a lot heavier than lithium, and battery cells with sodium-ion technology also have a lower energy density. But they also offer around 40 percent lower battery costs which is a significant benefit to drive the use of electromobility and accelerate acceptance from vehicle owners. Electric vehicles with sodium ion batteries (SIB) could be made available at price points possibly even lower than those of the traditional internal combustion engines.
But are sodium ion cells also less demanding when it comes to their industrial production? Or should the same focus on care be taken with quality assurance as is for lithium-ion cells? We will try to answer these questions here.
