| titleOfInvention | A polythiophene compound, a silicon negative electrode additive containing a polythiophene compound, and a silicon negative electrode material |
| abstract | The invention discloses a polythiophene compound, a silicon negative electrode additive containing the polythiophene compound and a silicon negative electrode material. Among them, the preparation method of polythiophene compounds is as follows: first, 3-methoxythiophene and PEG400 with a degree of polymerization of 9 are subjected to a substitution reaction to obtain a 3-position PEG400-substituted thiophene monomer, and then the 3-position PEG400-substituted thiophene monomer is chemically Oxidative polymerization reaction, that is. The polythiophene compound prepared in the present invention is compounded with lithium salt to obtain a silicon negative electrode additive, which can form a coating layer with both ion and electronic conductivity on the surface of the silicon negative electrode, and does not affect the electrode while coping with the volume expansion of the silicon negative electrode material. The conductivity of the material can effectively improve the battery cycle performance. |
