Abstract
This application provides a negative electrode plate, including an active layer 1 and an active layer 2. The active layer 1 contains an active material 1, and the active layer 2 contains an active material 2. A powder OI value of the active material 1 falls in a range of 8 to 32, and a powder OI value of the active material 2 falls in a range of 2 to 7. A gram capacity of the active material 1 falls in a range of 290 to 350 mAh/g, and a gram capacity of the active material 2 falls in a range of 350 to 368 mAh/g. A ratio α of the powder OI value between the active material 1 and the active material 2 falls in a range of 2.00 to 6.25.
