Abstract: A multi-layer current collector for an anodeless lithium-metal cells is described. The multi-layer current collector includes a current collector layer, a seed layer disposed on the current collector layer, and a protective shield layer disposed on the current collector layer. When incorporated into a Li-metal cell along with an electrolyte, charging of the cell leads to Li ion transferring through the shield layer, saturating the seed layer and ultimately forming a new Li metal layer between the shield layer and the lithiated seed layer. Discharging the cell reverses this process and results in disappearance of the Li metal layer and lithium passes back through the shield layer and into the electrolyte. The lithium in the seed layer also passes back into the electrolyte such that the current collector reverts to its initial structure prior to charging.

Abstract: Described herein are various embodiments of methods of making an all-solid-state electrode material for a rechargeable battery comprising in a first mixing step, mixing one of a transition metal phosphide, a transition metal oxide, and a transition metal sulfide with sulfur to produce a first mixture, in a first heat-treating step, heating the first mixture to a temperature ranging between about 250 degrees C. and about 450 degrees C. to produce a heat-treated second mixture comprising an active material and a glass former/electrolyte precursor, in a second mixing step, mixing the second mixture with a glass/electrolyte modifier to produce a third mixture, and permitting the third mixture to react to produce the cathode material, the cathode material comprising the active material and a solid state electrolyte. Electrode materials, electrodes, and batteries made using the foregoing and similar methods are also described.
