The utility model relates to a coating system. A substrate (10) includes a first coating region (11) and a second coating region (13) adjacent to the first coating region (11). The coating system includes a first gravure mechanism (100) and a second gravure mechanism (200), where the first gravure mechanism (100) is configured to apply a first functional layer (20) onto the first coating region (11), and the second gravure mechanism (200) can receive the substrate (10) having the first functional layer (20) and apply a second functional layer (30) made of a material different from that of the first functional layer (20) onto the second coating region (13). In the coating system, with provision of first gravure mechanism (100) and the second gravure mechanism (200), when the substrate (10) is continuously transported in a same direction, the two functional layers made of different materials can be sequentially applied onto corresponding regions of the substrate (10), and then an active material layer is applied, facilitating improving continuity and efficiency of coating and decreasing a scrap rate and defect rate of the substrate (10).
