Abstract

A battery polar plate coating system and method are disclosed. The system includes a coating machine head (4), a drying oven (3) and a winding device (1). The winding device is provided with N independent winding modules, with the N being an integer and not less than 2. The coating machine head is used for coating a foil belt with coating slurry (6). The foil belt is formed by adhering N foil subsidiary bets through an adhesive (2). Adjacent two foil subsidiary bets are expanded at the width direction of the foil belt and are partially overlapped. After the foil belt passes through the drying oven (adhesive force of the adhesive is lost due to heating functions), N polar plates are separated and are respectively wound by the N independent winding modules. The system and the method are easy to implement and the coating efficiency is high.
