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

A silicon negative electrode sheet includes: a current collector; and at least two active coatings containing negative active materials, which are sequentially coated on the current collector. Through holes are formed on the active coating along the thickness direction and are arranged at intervals. The liquid holding capacity of the silicon negative electrode sheet and the charging capacity of a silicon negative electrode can be improved.
