Abstract
The application relates to a coating method and a coating system. The method comprises the following steps: obtaining first online thickness data of a pole piece material belt; determining the position and size of a first film area of a first surface in the pole piece material belt according to the change of the first online thickness data; the first film area is any one of film areas distributed in gaps along the belt running direction of the pole piece material belt on the first surface; determining the position and size of coating a second surface in the pole piece material belt according to the position and size of the first film area; the second surface is a surface opposite to the first surface in the pole piece material belt; and coating a second film area opposite to the first film area on the second surface according to the position and size of coating the second surface. The method can improve the finished product yield of the coated electrode material.
