Abstract: A negative electrode plate, an electrode assembly, a battery cell, a battery, and an electrical device are disclosed. The negative electrode plate includes: a negative current collector and a negative active material layer disposed on the negative current collector. A plurality of pore channels are disposed in the negative active material layer. The technical solution of this application reduces lithium plating on a surface of the negative electrode plate, and reduces the possibility of lithium dendrites growing and piercing the separator, thereby enhancing reliability of the battery.
