Abstract

A negative electrode active material, a battery, and an electric device are disclosed, and relate to the battery field. A particle size D<v>50 of the negative electrode active material is a µm, a specific surface area is b m<2>/g, and 20 ≤ 2.5 × a + b ≤ 40. The battery includes a positive electrode plate, a negative electrode plate, and an electrolyte, where the negative electrode plate includes a negative electrode current collector and a negative electrode active material layer disposed on at least one surface of the negative electrode current collector, the negative electrode active material layer including the above negative electrode active material. The negative electrode active material, the battery, and the electric device of embodiments of the present application can improve the low-temperature discharge capability of the battery and increase the low-temperature discharge capacity retention rate thereof.
