DRIVE
November 1, 2023
The present application discloses a negative electrode plate, a secondary battery, and an apparatus containing the secondary battery. The negative electrode plate includes: a negative electrode current collector, including an organic support layer and a metal conductive layer disposed on the organic support layer; and a negative electrode active material layer, including at least a first active material layer, the first active material layer being disposed on the metal conductive layer and including 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; 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 d in 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 the second direction.
