Provided is a method of preparing a lithium metal anodeincluding forming a
current collector on a substrate that includes a release component;
depositing a lithium metal on the current collector; and releasing the
current collector with the deposited lithium metal from the substrate.
The method may produce a lithium metal anode with a clean lithium surface
and a current collector with a small thickness. The lithium metal anode
may be used to increase the energy density of a battery.
