Abstract

A coating die and a coating apparatus for a battery electrode plate are provided. The coating die includes a first die (1) and a second die (2). The first die (1) includes a first main body (11) and a first component (12), where the first component (12) is detachably connected to the first main body (11). The second die (2) and the first die (1) are arranged along a first direction (Z). A cavity (3) for accommodating a slurry is formed between the second die (2) and the first main body (11). A discharge port (4) in communication with the cavity (3) is formed between the first component (12) and the second die (2). When the first component (12) is worn, the worn first component (12) only needs to be removed, and a new first component (12) is installed, thereby reducing the downtime of the coating die, improving the coating efficiency, and reducing the production costs.
