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