Ultrathin electrochemical layer tailoring of lithiophilic materials with 3D hierarchical configuration for lithium metal batteries: Sn/Cu6Sn5@Cu2+1O nanowires on Cu foam

A hierarchical Cu 2+1 O nanowire covered ultrathin Sn/Cu 6 Sn 5 alloy composite on copper foam is produced in 90 minutes by a fully electrochemical wet process for use as a stable Li metal anode to prevent the formation of Li dendrite.
