Abstract
A metal anode including a metal anode body and a protective layer formed on one or two side surfaces of the metal anode body. The protective layer includes a coordination polymer having an unsaturated metal site or a complexation product formed by complexation between the coordination polymer having the unsaturated metal site and anions of battery electrolyte salt. The coordination polymer uses zirconium, aluminum, or iron as a center and uses R—Xas an organic ligand, R is n-valent hydrocarbyl, substituted hydrocarbyl, or hydrocarboxy, n is an integer in a range of 1 to 4, X is an oxygen-containing functional group capable of forming metal-oxygen chemical bond with the metal anode body, and the metal-oxygen chemical bond is formed between metal atoms on a surface of the metal anode body and oxygen atoms in the X group.
