Li-Ion batteries may power all the portable devices on Earth, not to mention the electric vehicles, houses, and energy storage facilities. Nevertheless, scientists are always on the lookout for new types of batteries, and sodium-sulfur chemistry seems like a promising alternative. That is if engineers solve their low energy density and short life span.
Researchers are experimenting with various battery chemistries in search of the “holy grail” of energy storage medium. Not because the Li-Ion batteries widely used today are imperfect (they are). But because lithium is becoming more problematic to source, and other raw materials are becoming expensive and scarce. One of the more promising materials to replace lithium is sodium. Sodium batteries have been in development for a very long time thanks to being cheaper and more stable.
