| titleOfInvention | Preparation method of composite positive electrode material for lithium battery |
| abstract | The invention discloses a preparation method of a composite cathode material for a lithium battery, which comprises the following steps: ultrasonically dispersing graphene oxide in deionized water, adding cerium acetate, potassium acetate, urea and ammonia water into a container, and preparing a cerium oxide/graphene compound through sealing, baking, drying and microwave treatment; preparing rare earth metal ion doped lithium iron phosphate by using lithium hydroxide, iron phosphate, oxalic acid, glucose and rare earth metal oxide as raw materials; preparing cerium oxide/graphene/rare earth metal ion-doped lithium iron phosphate by performing ultrasonic dispersion and ball milling on a cerium oxide/graphene compound, rare earth metal ion-doped lithium iron phosphate and ethanol; the composite cathode material for the lithium battery is prepared by taking lithium hydroxide, ferric vanadate, phosphoric acid, deionized water and cerium oxide/graphene/rare earth metal ion-doped lithium iron phosphate as raw materials, and stirring, microwave and calcining the raw materials. The composite cathode material prepared by the invention has excellent electrical property; meanwhile, the preparation method is clean and environment-friendly. |
