| titleOfInvention | Negative electrode material and preparation method thereof |
| abstract | The invention discloses a negative electrode material and a preparation method thereof, wherein the negative electrode material comprises a three-dimensional porous framework and elemental silicon loaded on the three-dimensional porous framework, the three-dimensional porous framework is a composite framework containing metal and carbon, and the metal and the carbon in the three-dimensional porous framework exist in the form of elemental silicon; the metal is selected from any one or more of copper, iron, manganese, cobalt, tin, nickel, magnesium, titanium, aluminum or zinc. According to the cathode material, a composite framework formed by metal and carbon has excellent toughness and an ordered pore structure, the volume effect of silicon in the process of embedding and removing lithium ions can be buffered, the structural stability of the cathode material is enhanced, and the cycle stability of a cathode is improved; and the metal and carbon have excellent conductivity, and the electrochemical performance of the cathode material is effectively improved by compounding with silicon. |
