The negative electrode piece comprises a first anode current-collecting layer, and the first anode current-collecting layer completely covers the surface of the electric-conductive lithium-intercalatable anode layer and conductively contacts with the electric-conductive lithium-intercalatable anode layer tightly. The first anode current-collecting layer is an electron conductive layer that has a through-pore structure and a thickness of 1 to 2000 μm. The first anode current-collecting layer has a pore diameter of 10 to 800 μm, and the through-pore has a porosity of 10% to 90%. The first anode current-collecting layer is on the two sides of the electric-conductive lithium-intercalatable anode layer. Under the condition that the electric-conductive lithium-intercalatable anode layer contains the electric-conductive lithium-intercalatable anode particles in accumulated state, the first anode current-collecting layer also plays a role of sealing, which prevents the lithium-intercalatable anode material in the electric-conductive lithium-intercalatable anode layer from dropping off and influencing the performance of the battery, and in addition it also better ensures the flatness of the surface of the pole piece.
