  "textContent": "A negative electrode plate includes: a negative electrode current collector, and a negative electrode film layer located on at least one surface of the negative electrode current collector and including first and second negative electrode active material particles. The first negative electrode active material particles includes adsorption holes and have a tap density of 0.4 g/cm-1.4 g/cm. The second negative electrode active material particles have a layered structure and a tap density of 0.05 g/cm-1.5 g/cm. Based on the total mass of the first and second negative electrode active material particles, a mass percentage of the first negative electrode active material particles is in the range of 70%-95%, and a mass percentage of the second negative electrode active material particles is in the range of 5%-30%. A compaction density PD of the negative electrode film layer satisfies: 0.8 g/cm≤PD≤1.3 g/cm.",
