| titleOfInvention | Preparation method of composite negative electrode pre-embedded lithium material |
| abstract | The invention belongs to the field of preparation of lithium battery materials, and particularly relates to a preparation method of a composite negative electrode pre-embedded lithium material, which is characterized by comprising the following steps of: the method comprises the following steps: (1) mixing Li a M b Mixing with an organic carbon source to obtain mixed powder Li a M b Organic carbon source, wherein the organic carbon source is one or more of asphalt, resin, glucose and starch, and the organic carbon source accounts for Li a M b 1-5% of the mass, and the mixing mode is dry mixing or wet mixing; (2) mixing the mixed powder Li obtained in the step (1) a M b Drying organic carbon source and calcining to obtain coated product Li a M b C; (3) coating the product Li obtained in the step (2) a M b C and SiO x Weighing according to a certain mass percentage, and performing ball milling to obtain the composite cathode pre-embedded lithium material Li a M b /C/SiO x (ii) a Wherein a is more than 1, M is one or more of O, N, P, S, Si and C, b is more than or equal to 1, and x is more than 0 and less than 2. The composite negative electrode pre-embedded lithium material provided by the invention has strong conductivity and good stabilizing effect in air. |
