Zusammenfassung:	The invention relates to a high-entropy oxide coating with a core-shell structure and a preparation method and application thereof, and belongs to the technical field of anode coatings. The preparation method comprises the following steps that S1, high-entropy alloy powder is placed in a powder feeder, the high-entropy alloy powder is deposited on the surface of a base body through the atmosphere plasma spraying technology, and a high-entropy oxide coating is obtained; the high-entropy alloy powder is obtained by uniformly mixing at least five metal elements and drying; the molar ratios of all metal elements in the high-entropy alloy powder are equal; and S2, the powder feeder is closed, other parameters are not changed, spraying heating is conducted on the high-entropy oxide coating in the step S1, and the high-entropy oxide coating of the core-shell structure is obtained. According to the preparation method, due to the high-entropy effect of the high-entropy oxide and the use of the atmospheric plasma spray
