  "textContent": "Provided are a negative electrode material and a preparation method thereof and a lithium ion battery, specifically relating to the technical field of lithium ion batteries. The Young's modulus E of the negative electrode material has a value of: 8 GPa≤E≤17 Gpa, the negative electrode material includes natural graphite and a coating layer coated on the surface of the natural graphite. The negative electrode material of the disclosure has a relatively high Young's modulus, may better maintain the microscopic crystal structure when lithium ions deintercalate, undergoes smaller irreversible deformation, and has better cycle performance.",
