| titleOfInvention | Battery negative plate, preparation method thereof and lithium ion battery |
| abstract | The invention relates to the technical field of lithium ion batteries, and particularly provides a battery negative plate, a preparation method thereof and a lithium ion battery. The battery negative plate comprises a negative current collector and a negative material layer attached to the surface of the negative current collector, the materials forming the negative material layer comprise a silicon material, a conductive agent and a binder, and the silicon material, the conductive agent and the binder are (5-10) to (1-3) in mass ratio; the binder is a lignin crosslinking modified product. The battery negative plate has excellent mechanical strength and mechanical compressive capacity, and limits the silicon material in a certain area, so that the silicon material is subjected to volume deformation in a limited space, and simultaneously, silicon particles are prevented from slipping or being separated from the copper foil, so that the integrity of an electrode conductive network is ensured, the mechanical integrity of the electrode is maintained, and the electrochemical performance of the silicon negative electrode is greatly improved. |
