<p>Batteries including a lithium anode stabilized with a metal-lithium alloy and battery cells comprising such anodes are provided. In one embodiment, an electrochemical cell having an anode and a sulfur electrode including at least one of elemental sulfur, lithium sulfide, and a lithium polysulfide is provided. The anode (130) includes a lithium core (102) and an aluminum-lithium alloy layer (106) over the lithium core. In another embodiment, a surface coating (108), which is effective to increase cycle life and storageability of the electrochemical cell, is formed on the anode. In a more particular embodiment, the anode is in an electrolyte solution (110), and, more particularly, an electrolyte solution including either elemental sulfur, a sulfide, or a polysulfide where the surface coating is composed of Al2S3.</p> |
