Abstract
A negative electrode sheet and a battery applying the same are provided. The negative electrode sheet includes a current collector and a negative electrode active coating disposed on two opposite surfaces of the current collector. The negative electrode active coating contains a negative electrode active material, and the negative electrode active material includes graphite. The negative electrode sheet satisfies 0.0025≤ε*ρ/PD≤0.0065, where ε is a porosity of the negative electrode sheet, ρ is a surface density of a single surface of the negative electrode sheet with a unit of g/cm, and PD is a compacted density of the negative electrode sheet with a unit of g/cm. The compacted density PD, the surface density ρ, and the electrode sheet porosity ε of the negative electrode sheet form specific correlation relationships among one another.
