Lithium metal anodes demonstrate inferior cycling stability due to uncontrolled Li deposition and large volume fluctuation. Composite Li metal anodes with a 3D host show stable Li deposition. Nevertheless, the advantages of a host are achieved by the joint effect of various parameters. The effect of...
