NOVELTY - Preparing negative electrode material involves weighing solid components and solvent. The solid components includes negative active material, conductive agent, binder and additives. The additives includes lithium hydroxide, and added amount is negative electrode of 0.2-5% of active material. The negative electrode active material, conductive agent and binder are uniformly mixed, and portion of the solvent is mixed uniformly, negative electrode active slurry is obtained. The additives are dissolved in the remaining solvent, and added to the negative active slurry, and mixed uniformly to obtain mixed slurry. The mixed slurry is dried. The lithium hydroxide is distributed on the surface of the negative electrode active material to obtain negative electrode material. USE - Method for preparing negative electrode material for lithium ion battery (claimed). ADVANTAGE - The method enables to prepare negative electrode material that inhibits the side reaction between the electrolyte and negative electrode active material, improves the cycle performance of the lithium ion battery. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) a lithium ion battery negative electrode sheet, which comprises negative electrode current collector and negative electrode material which are arranged on both sides of the negative electrode current collector, and negative electrode material; (2) a lithium ion battery cell, which comprises negative electrode material of lithium ion battery; and (3) a lithium-ion battery pack, which comprises lithium-ion battery cell, and lithium-ion battery cell comprises lithium-ion battery negative electrode material.
