| titleOfInvention | A kind of preparation method of nanometer niobium dioxide/carbon lithium ion battery negative electrode material |
| abstract | The invention discloses a preparation method of a nanometer niobium dioxide/carbon lithium ion battery negative electrode material. The invention uses acrylic resin as the solvent of the niobium dioxide precursor, so that the niobium dioxide precursor and the resin are uniformly mixed and dispersed, and the nanometer niobium dioxide particles generated in situ during the calcination process can be uniformly dispersed in the carbon matrix. By adjusting the ratio of resin and niobium dioxide precursor, the selection of calcination temperature and time, the appropriate nano-niobium dioxide particle size and crystal form can be obtained, and nano-niobium dioxide/ carbon composite. Using the material of the present invention as a new type of negative electrode material for lithium ion batteries has a higher theoretical specific capacity than niobium pentoxide, and at the same time, the nano-scale particles can shorten the diffusion distance of lithium ions in the process of de-intercalation, and the uniformly coated carbon material can improve the Conductivity of composite materials. |
