Sodium-Sulphur Battery with Longer Life and Energy Density

The article Researchers develop sodium-sulphur battery with longer lifespan and energy density by Felix Baumann first appeared on BASIC thinking. Our newsletter keeps you up to date. Researchers from the Max Planck Institute and the British-Australian battery manufacturer Gelion have developed a sodium-sulphur battery that is supposed to have a significantly longer lifespan and energy density than previous batteries. The Max Planck Institute for…

We have to move away from rare and expensive raw materials in batteries to secure the electric future. Sulphur, for example, occurs much more frequently in the earth's crust than lithium and is therefore much cheaper to have. However, the reaction-loving element forms polysulphides and becomes unusable after only a few charges. However, the energy density can compete with lithium. Coal-based nanostructures help stabilize the sulphur and thus mak…
