Abstract: Disclosed is a metal anode, including a metal anode body (10) and a protective layer (11) formed on one or two side surfaces of the metal anode body (10). The protective layer (11) 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—Xn as 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 (10), and the metal-oxygen chemical bond is formed between metal atoms on a surface of the metal anode body (10) and oxygen atoms in the X group.anodeanode.

Abstract: This application provides a battery electrolytic solution, including an electrolyte salt and a non-aqueous organic solvent. The non-aqueous organic solvent includes a first organic solvent shown in a formula (I) and/or a second organic solvent shown in a formula (II): R1—S(═O)x—N(—R3)—R2 formula (I); and R1—S(═O)x—N(—R3)—S(═O)y—R4 formula (II). R1 and R4 are separately selected from fluoroalkyl, fluoroalkoxy, fluoroalkenyl, fluoroalkenyloxy, fluoroaryl, or fluoroaryloxy. R2 and R3 are separately selected from alkyl, alkoxy, alkenyl, alkenyloxy, aryl, or aryloxy. x is 1 or 2, and y is 1 or 2. A total content in mass of the first organic solvent and/or the second organic solvent in the electrolytic solution ranges from 10% to 90%. The electrolytic solution includes the first organic solvent and/or the second organic solvent of a high content in mass.
