Abstract
An anode for a lithium metal battery includes a host structure configured to be between an anode current collector and a separator, the host structure having void spaces configured to host metallic lithium during charging, wherein the host structure has a void space of ≥60% and ≤80%. Another anode for a lithium metal battery includes a current collector, a separator, and a host structure between the current collector and the separator, the host structure having void spaces configured to host metallic lithium during charging, wherein the host structure is formed of fibers.
