Abstract: A coating die head includes a first die block, a second die block, a third die block, and a fourth die block that are sequentially arranged at intervals. The first die block and the second die block form a first slot therebetween, the second die block and the third die block form a second slot therebetween, and the third die block and the fourth die block form a third slot therebetween. Each of the first die block, the second die block, the third die block, and the fourth die block has a die lip at a surface thereof. A length of the die lip of the second die block ranges from 100 micrometers to 200 micrometers. A ratio of a length of the die lip of the third die block to the length of the die lip of the second die block ranges from 1.5 to 7.
