NEGATIVE ELECTRODE SHEET, SECONDARY BATTERY, BATTERY MODULE, BATTERY PACK, AND ELECTRIC DEVICE

This application discloses a negative electrode plate, a secondary battery, a battery module, a battery pack, and an electric apparatus. The negative electrode plate disclosed in this application includes a negative electrode current collector and active material layers disposed on at least one surface of the negative electrode current collector. The active material layers include a first active material layer and a second active material layer disposed on a surface of the first active material layer. The first active material layer includes a first active material, the second active material layer includes a second active material, and the active material layers satisfy α×CW≤CW, α being a relative factor of layer spacings, where α = d 2 d 1 and 1≤α≤1.12. Using a secondary battery obtained by using the negative electrode plate of this application can improve both rate performance and energy density of the battery.
