The invention relates to a novel efficient iron removal device for lithium battery diaphragm coating slurry, which comprises an upper cover, a shell, a feed port, a discharge port, a drain outlet anda magnetic bar, wherein the upper cover covers the upper end of the shell; the feed port is formed in one end of the shell; the discharge port is formed in the other side end of the shell; the feed port is communicated with the discharge port; the lower end of the discharge port is connected with the drain outlet; and the magnetic bar is arranged on the outer wall of the lower end of the upper cover. After slurry enters the device, the slurry flows through the lower wall of the upper cover, magnetic substances are adsorbed, and the magnetic substances are directly adsorbed on the magnetic rodalong with the increase of the slurry and contact with the magnetic bar; during cleaning, the drain outlet is opened, slurry is discharged, the upper cover of the iron removal device is taken out, themagnetic bar is separated
