SILICON NEGATIVE ELECTRODE SHEET, MANUFACTURING METHOD THEREOF AND LITHIUM ION BATTERY

A silicon negative electrode sheet (100) including: a current collector (110); and at least two active coating layers (120) containing negative active materials, which are sequentially coated on the current collector (110). Through holes (130) are formed in the active coating layers (120) extending vertically through the respective active coating layer and being arranged at intervals. By the embodiment of the present invention, the liquid holding capacity of the silicon negative electrode sheet (100) and the charging capacity of a silicon negative electrode are improved.
