Abstract: The invention discloses a coating apparatus for coating slurry on a substrate. The coating apparatus comprises: a container for storing the slurry; a slurry pushing means connecting with the container through a discharging pipe; a coating head connecting with the slurry pushing means through another discharging pipe and connecting with the container through a feed-back pipe, and a controlling valve provided within the feed-back pipe. The coating head comprises: a coating slit; a discharging concave; a feed-back concave; a separator provided between the feed-back concave and the discharging concave; and an extending concave for correspondingly covering and matching with the discharging concave and the feed-back concave. The discharging concave and the feed-back concave are respectively provided with a discharging aperture and a feed-back aperture for respectively connecting with the discharging pipe and the feed-back pipe.

Abstract: A separator includes a separator body and a first film. The separator body is formed by mixing and solidifying a first material and a second material and then removing the first material by an alkaline liquid etching process. The separator body has a plurality of irregular holes formed corresponding to the removed first material. The first film is disposed on one side of the separator body.
