  "textContent": "The present disclosure provides a pre-lithiated silicon negative electrode material, a silicon negative electrode plate, a method for preparing the same, and a lithium-ion battery. The pre-lithiated silicon negative electrode material includes a silicon negative electrode material and a lithium-containing polymer compounded with the silicon negative electrode material. The lithium-containing polymer includes a polymer shown in the following formula 1, where x is 1 to 12, and R1 is I; or II, where y is 1 to 4; or III or IV The use of the pre-lithiated silicon negative electrode material can improve performance, such as initial Coulombic efficiency, of a lithium-ion battery.",
