Negative plate used for lithium ion battery and preparation method thereof

The invention provides an integrative negative plate used for a lithium ion battery. The integrative negative plate is prepared from negative electrode materials and metal powder, wherein the metal powder does not form alloy with metal lithium. The invention also provides a preparation method of the integrative negative plate and the lithium ion battery which contains the above integrative negative plate. The integrative negative plate has good comprehensive performance and excellent negative plate conductivity, and the specific energy density of the unit volume or the unit mass of the battery is greater than the specific energy density of a common lithium ion battery.
