Anode plate for lithium ionic cell and preparation thereof

The invention provides a negative sheet for a lithium ion battery, which comprises a collector body and a negative active material layer coated on the collector body. The negative active material comprises a component A and a component B. The component A is simple-substance silicon; the component B is one or some of copper, titanium, aluminum, iron, nickel, zinc and cobalt, wherein the negative active material layer is of a porous structure. The invention also provides a preparation method of the negative sheet for the lithium ion battery. The negative active material layer of the negative sheet for the lithium ion battery is of a porous structure, thereby ensuring that the negative active material can carry out volume expansion through a hole, effectively abating the fall-off of the negative active material on the negative sheet, and improving the cycle performance of the lithium ion battery with the negative sheet.
