| titleOfInvention | Positive electrode material precursor and preparation method thereof and positive electrode and preparation method thereof |
| abstract | The present invention provides a kind of preparation methods of positive electrode material precursor, comprising the following steps: mixes by nickel compound containing, cobalt compound and containing manganese compound, obtains mixed solution；The mixed solution, complexing agent, precipitating reagent are mixed with metallic colloid presoma, positive electrode material precursor is obtained after reaction.During above-mentioned preparation positive electrode material precursor, pass through coprecipitation reaction, nano metallic colloid is set to form electric double layer on presoma surface, inhibit the growth of presoma primary particle thickness, reduce the interlamellar spacing of primary particle lamellar structure, prepare by hexagonal plate structured aggregate at precursor of lithium ionic cell positive material.Present invention also provides a kind of positive electrodes being prepared by positive electrode material precursor.The hexagonal plate primary particle that the application prepares positive electrode has smaller lithium ion mobility path, more preferably electrolyte wellability, and the high rate performance of positive electrode can be improved, be particularly suitable for the manufacture of lithium-ion-power cell. |
