Anode structure for a lithium metal battery

Abstract:

An anode for a lithium metal battery includes a current collector, a seed layer deposited onto the current collector, the seed layer comprising a seed material selected to promote electrochemical plating of metallic lithium onto the seed layer, a separator, a host structure between the seed layer and the separator, the host structure having void spaces configured to host metallic lithium during charging, a first adhesion layer bonding the host structure to the seed layer, and a second adhesion layer bonding the host structure to the separator.
