Abstract: An anode including a current collector and an anode active material layer disposed on the current collector are provided. The anode active material layer includes first oriented particles having a first tilt angle θ1 inclined with respect to the direction parallel to the current collector, and second oriented particles having a second tilt angle θ2 inclined with respect to the direction parallel to the current collector. The first tilt angle θ1 and the second tilt angle θ2 are different and both not greater than 70°.

Abstract: 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.
