| titleOfInvention | Heterogeneous element doped ferroferric oxide/graphene negative electrode material |
| abstract | The heterogeneous element doped ferroferric oxide/graphene negative electrode material is prepared by the following method: providing a ferric salt solution; providing a heterogeneous metal salt solution; providing a precipitant solution; dripping the heterogeneous metal salt solution into an iron salt solution to obtain a mixed metal salt solution; stirring and dripping a precipitator solution into the mixed metal salt solution to obtain a mixed solution; carrying out solvothermal reaction on the mixed solution in a closed reaction kettle; centrifuging to obtain a precipitate; dispersing the precipitate into a graphene aqueous solution to form a suspension; freeze-drying the suspension to obtain a sponge-like composite material; and carbonizing the resulting composite material to form a negative electrode material for a sodium ion battery. The invention obviously improves the reversible cycle specific capacity of the ferroferric oxide in the secondary new energy sodium ion battery, enhances the stability of the battery during the cycle, realizes the high-capacity and high-rate quick charge and discharge of the battery, and leads the ferroferric oxide to be used as a cathode material and have wider application prospect in the field of new energy. |
