Abstract
Stabilized lithium particles include a lithium-containing core and a coating of a complex lithium salt that surrounds and encapsulates the core. The coating, which is a barrier to oxygen and water, enables the particles to be handled in the open air and incorporated directly into electrochemical devices. The coating material is compatible, for example, with electrolytic materials that are used in electrochemical cells. The average coated particle size is less than 500 microns.
