  "textContent": "The present application provides a negative electrode sheet and a battery. The negative electrode sheet includes a negative current collector and a negative electrode film provided on at least one surface of the negative current collector and including a negative active material, and the negative electrode film satisfies: 4≤P×[(30−Dv50)/2+2×(10−M)]≤20. P represents a porosity of the negative electrode film; Dv50 represents a volume median particle diameter of the negative active material, and a unit is μm; M represents a capacity per unit area of a negative electrode film, and a unit is mAh/cm. The negative electrode sheet of the present application has the characteristics of excellent dynamics performance, and the battery of the present application also has the characteristics of excellent dynamics performance, long cycle life and high energy density at the same time.",
