A negative electrode sheet, a battery cell, a battery pack, and an electricity-consumption device are involved in the disclosure. The negative electrode sheet includes a negative-electrode current collector and a negative-electrode material layer. The negative-electrode material layer is disposed on a surface of the negative-electrode current collector and includes a first active material. The first active material includes a first particle cluster and a second particle cluster. A compaction density of the first particle cluster after being compressed at a pressure of 5 tons is P1, and a compaction density of the second particle cluster after being compressed at a pressure of 5 tons is P2, where P1 and P2 satisfy: 1.0 ≤ P1/P2 ≤ 1.5. When a volume percentage in the first particle cluster reaches 50%, a corresponding particle size value Dv50 satisfies: 13 µm ≤ Dv50 ≤ 20 µm, and when a volume percentage in the second particle cluster reaches 50%, a corresponding particle size value Dv50' satisfies: 5 µm ≤ Dv50' ≤ 12 µm. In the case where the negative electrode is applied in the battery cell, the battery cell may have a relatively high energy density and a relatively good cycling performance.
