The positive electrode plate includes a first surface and a second surface opposite to each other in a first direction, the positive electrode plate is provided with a plurality of protruding portions and straight portions located between the adjacent protruding portions. A maximum distance from a vertex of the protruding portion to a plane where the first surface is located is h, in the first direction, a thickness of the straight portion on the positive electrode plate is h, and 5%≤h/h≤30%. A weight percentage content of a silicon element in a negative electrode active layer of the negative electrode plate is W, and 0.3≤W/(h/h)≤5.",
