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.
