NEGATIVE ELECTRODE SHEET AND METHOD FOR PREPARING THE SAME, SECONDARY BATTERY, BATTERY MODULE, BATTERY PACK, AND DEVICE

A negative electrode sheet includes a current collector, and a first active material layer and a second active material layer that are sequentially provided on at least one surface of the current collector. The first active material layer includes a first negative electrode active material. Particle sizes of the first negative electrode active material satisfy: 0.02≤A=(Dn10)/(Dv50)≤0.2. The second active material layer includes a second negative electrode active material. Particle sizes of the second negative electrode active material satisfy: 0.02≤A=(Dn10)/(Dv50)≤0.3; and Aand Asatisfy 1
