description The invention belongs to a lithium-ion battery negative electrode and a lithium-ion battery. The lithium-ion battery negative electrode comprises a negative current collector and a negative coating arranged on the surface of the negative current collector. The full width at half maximum W of the D002 peak of the negative coating ranges from 0.11 degrees to 0.17 degrees, the compaction density Rhoof the negative coating ranges from 1.1g/m to 1.8g/m , and the product of the full width at half maximum W and the compaction density Rho ranges from 0.12 to 0.30. The preparation of the negativecoating and the lithium-ion battery negative electrode is realized by limiting the range of the full width at half maximum W of the D002 peak of the negative coating, the range of the compaction density Rho of the negative coating and the range of the product of the full width at half maximum W and the compaction density Rho. The electrochemical reactivity of the negative electrode material can be improved to the maximum. The
