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°.

Abstract: A negative electrode active material having a specific aspect ratio and sphericity in a cumulative particle volume distribution. When tested by using a dynamic particle image analyzer, when a cumulative particle volume distribution of the negative electrode active material is 10%, an aspect ratio AR10 of the negative electrode active material satisfies 0.4≤AR10≤0.55, and a sphericity S10 of the negative electrode active material satisfies 0.48≤S10≤0.60. The negative electrode active material improves rate performance, dynamics performance, and a deformation problem of the electrochemical apparatus.

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°.
