| titleOfInvention | A kind of preparation method of anode material for high-voltage lithium ion of nucleocapsid structure |
| abstract | The invention provides a kind of preparation method of anode material for high-voltage lithium ion of nucleocapsid structure, described anode material for high-voltage lithium ion is nucleocapsid structure, and its core layer material is LiNin 0.5-x mn x mnn 1.5 on 4 , wherein x is 0.002 ~ 0.12, M=Co, Al, Cr, Cu or Fe; Shell Materials is LiNin 0.5 mnn 1.5 on 4 , the mass fraction that Shell Materials accounts for core layer material is 2 ~ 20%.Its preparation method is: the presoma being prepared nucleocapsid structure by coprecipitation, then prepares the anode material for high-voltage lithium ion of nucleocapsid structure through high-temperature calcination and annealing in process.In this material, core layer material is by doping high-valence state element, the chemical valence of part manganese is made to reduce to positive trivalent by positive tetravalence, manganic existence improves the high rate performance of material, and due to doped chemical participate within the scope of high voltage discharge and recharge reaction, material capacity does not reduce.Shell Materials is not containing Mnn 3+ , avoid the problems of dissolution of the manganese that manganic causes, improve material circulation performance. |
