| titleOfInvention | A kind of lithium ion battery cathode material and preparation method thereof |
| abstract | The invention discloses a positive electrode material for a lithium ion battery and a preparation method thereof, comprising the following steps: adding oleic acid to an organic solvent A, adding a lithium source after mixing, and dissolving to obtain a first solution; The compound is dissolved in organic solvent B to obtain a second solution; the first solution and the second solution are mixed and heated to obtain a mixed gel; the mixed gel is dried, pulverized and then heat-treated in an inert atmosphere to obtain a positive electrode for a lithium ion battery Material. The Li 2 MSiO 4 /C composite nanomaterial prepared by the invention is used as the positive electrode material of the lithium ion battery, which effectively realizes the high capacity charge-discharge and high cycle stability of the battery. When M is manganese, the capacity retention rate can be as high as 49.4%, When M is iron, the cycle retention rate is as high as 94.35%. |
