Negative electrode plate, secondary battery, and apparatus contianing the secondary battery

A negative electrode plate, comprising:

• a negative electrode current collector, comprising an organic support layer and a metal conductive layer disposed on at least one surface of the organic support layer;
• a negative electrode active material layer, comprising at least a first active material layer, the first active material layer being disposed on the surface of the metal conductive layer away from the organic support layer, and the first active material layer comprising a first active material;
• wherein in a first cross section in a thickness direction of the negative electrode plate, the first active material has a size a in a direction parallel to the metal conductive layer, the first active material has a size b in the thickness direction, and a and b satisfy 0.8≤a/b≤20;
• and
• in a second cross section in the thickness direction of the negative electrode plate, the first active material has a size c in the direction parallel to the metal conductive layer, the first active material has a size din the thickness direction, and c and d satisfy 0.8≤c/d≤20;
• and
• the first cross section is parallel to a first direction, the second cross section is parallel to a second direction, and the first direction intersects with the second direction.
