Abstract
A lithium metal battery has a cathode current collector, a cathode active material layer, an electrolyte, and an anode current collector host structure interfacing with the electrolyte. The anode current collector host structure comprises a conductive layer, a non-conductive layer on the conductive layer, and recesses formed through the non-conductive layer and into the conductive layer, each recess having an opening in the non-conductive layer with a width that is smaller than a largest width of the recess.
