| titleOfInvention | Hexagonal ferric oxide/carbon negative electrode material and preparation method thereof |
| abstract | A hexagonal ferric oxide/carbon negative electrode material and a preparation method thereof are provided, wherein the negative electrode material is prepared by the following steps: (1) uniformly mixing water and N, N-dimethylformamide to obtain a uniform solution; (2) adding an iron source and an organic ligand, and stirring to obtain a mixed solution; (3) sealing, heating for reaction, cooling, filtering, washing and drying to obtain yellow powder; (4) roasting in inert atmosphere, and cooling to obtain the final product. The negative electrode material has the particle size of 3-5 mu m, belongs to a mesoporous material, is assembled into a battery, and is 100 mA.g at 3-0.01V ‑1 The first charge specific capacity reaches 923.5 mAh g ‑1 The capacity retention rate is more than or equal to 95 percent after 200 cycles of circulation, and the first discharge specific capacity reaches 1368.8 mAh g ‑1 The volume expansion is small in charge and discharge, the conductivity is good, the charge and discharge performance is stable, and the cycle performance is good; the method is simple, the reaction temperature is low, the period is short, and the cost is low. |
