| titleOfInvention | Preparation method for composite cathode material of lithium ion battery |
| abstract | The invention discloses a preparation method for a composite cathode material of a lithium ion battery by means of spray drying pyrolysis treatment. The preparation method includes the steps: dissolving a first type of binder organic carbon source into solvent of a proper quantity, adding a silicon source, a second type of binder and a dispersing agent, dispersing uniformly, adding graphite, dispersing for a certain time, subjecting uniformly dispersed suspension to spray drying, and using the first type of binder organic carbon source to bond the silicon source, the graphite and the second type of binder particles into spherical or spherical-like forms to obtain a composite precursor; and transferring the precursor into a shielding atmosphere for sintering, heating the second type of binder to a certain temperature to be melted into a liquid crystal state, bonding the particle silicon source and the graphite into cores, subjecting the organic carbon source to pyrolysis at the high temperature to form a coating, and furnace cooling to obtain the carbon-silicon composite cathode material of the lithium ion battery. The preparation method is simple, easy in implementation and high in practicality. The carbon-silicon composite prepared by the method has the advantages of high reversible capacity, designable capacity, high circulating performance and high-current discharging performance, high tap density and the like. |
