1. A supporter of lithium metal, wherein:
a material of the supporter of lithium metal is at least one of copper, an alloy of the copper, nickel, or an alloy of the nickel,
a surface of the supporter of lithium metal defines a lithiophilic surface,
the lithiophilic surface has a mainly Cu(100) orientation or a mainly Ni(100) orientation, and
when cyclic voltammograms of the supporter of lithium metal are detected in a Pb(ClO4)2 aqueous solution:
an area of an underpotential deposition peak of the supporter of lithium metal located at −0.39 V is greater than an area of an underpotential deposition peak of the supporter of lithium metal located at −0.35 V to obtain the mainly Cu(100) orientation or the mainly Ni(100) orientation, wherein the area of the underpotential deposition peak of the supporter of lithium metal located at −0.35 V is larger than 0.
