Negative electrode of rechargeable battery and manufacturing method thereof

A method for manufacturing a negative electrode of a rechargeable battery includes coating a first active mass on a first surface of a substrate, aligning a first graphite material in the first active mass, and coating a second active mass on a second surface of the substrate. The second active mass includes a second graphite material. The method also includes aligning the second graphite material and pressing the first and second graphite material. The alignment operations are performed by applying magnetic fields, so that a first long axis of the first graphite material forms a first acute angle with the first surface and a second long axis of the second graphite material forms a second acute angle with the second surface. The second long axis is inclined in a direction facing the first long axis, with the substrate therebetween.
