Abstract
Methods are proposed for manufacturing dendrite-resistant lithium metal electrodes suitable for incorporation into lithium metal batteries. In an embodiment, the method involves first electroplating a copper sheet onto a surface of a single crystal of silicon, the silicon being doped to form a p-type or an n-type semiconductor, and then further electroplating the copper sheet with lithium metal. The lithium-electroplated copper sheet thus manufactured provides a lithium electrode that is resistant to dendrite formation during cycling of lithium metal batteries when compared to conventionally manufactured lithium electrodes. Methods are further provided of manufacturing lithium sheets by directly electroplating lithium metal onto single crystals of doped silicon, the lithium sheets configured for incorporation into lithium metal electrodes that are resistant to dendrite formation during cycling of lithium metal batteries.
