Abstract: An aqueous lithium-ion battery and an electrode used therein are provided, wherein the electrode includes a current collector, a coating layer, and a composite layer. The coating layer is disposed on at least one surface of the current collector, and the coating layer contains an active material. The composite layer is disposed on a surface of the coating layer. The composite layer includes a first film and a second film, wherein the first film is between the second film and the surface of the coating layer, and the water contact angle of the first film is greater than the water contact angle of the second film.
