摘要： A method of edge sealing for a secondary lithium battery, including: (1) drawing a 3D model of a battery edge of a secondary lithium battery, and inputting it into a 3D printer; (2) positioning the secondary lithium battery in a 3D printing area, and fixing a relative position of the secondary lithium battery in the 3D printing area; (3) stimulating, by the 3D printer, the battery edge according to the 3D model and setting a printing path; (4) adding edge sealing glue in a printing head of the 3D printer, the printing head moves according to the set printing path and meantime performs at least one time of printing, so that printed edge sealing glue covers the battery edge; (5) solidifying the edge sealing glue. The method of edge sealing of this application has broader application, which can be applied to batteries of any shape.
