Abstract

The present application provides a coating device and coating method for an electrode assembly. The electrode assembly includes an electrode main body, the electrode main body has a first direction, a second direction and a third direction that are orthogonal to each other, and includes two main surfaces, two end surfaces, and two side surfaces, and the coating device includes a discharge assembly, a cutting assembly and a first coating assembly. The discharge assembly is used to store and release a material strip, which includes a plurality of coating films connected in sequence along a length direction of the material strip, and each coating film includes two main coating areas spaced apart from each other and a connecting area connected between the two main coating areas. The cutting assembly is used to cut a head end coating film located at a head end of the material strip from the material strip. The first coating assembly is used to coat the first of the two end surfaces with the connecting area of the head end coating film, and to coat each of the two main surfaces with corresponding one of the two main coating areas, so as to form an electrode coating body. Through the above manner, the action complexity of a coating process can be simplified.
