1. An electrochemical device, comprising an anode; the anode comprising a current collector and an anode active material layer disposed on the current collector; wherein
the anode active material layer comprises first oriented particles having a first tilt angle θ1 inclined with respect to a 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; wherein the first tilt angle θ1 and the second tilt angle θ2 are different, 0°≤θ1≤20°, and 20°<θ2≤70°; and
in the first oriented particles, particles having a particle size between 10 μm and 35 μm account for 7.0%-29.0%.
