New Liquid Metal Alloy Improves Sodium-Beta Batteries

Researchers at Pacific Northwest National Laboratory have developed a new liquid metal alloy. This animation shows how the new negative electrode - made of a sodium-cesium alloy, which is represented by orange and green balls - easily coats the solid ceramic electrolyte in sodium-beta batteries. The liquid metal alloy enables the batteries to operate at lower temperatures and last longer, while also streamlining their manufacturing process and reducing the risk of accidental fire.
