| titleOfInvention | Preparation method of cobalt/barium activated lithium iron phosphate anode material |
| abstract | The invention relates to a preparation method of a cobalt/barium activated lithium iron phosphate anode material, which comprises the following steps: mixing a lithium source, an iron source, a phosphate radical source, a cobalt source and a barium source at a ratio of 1mol Li : (0.00002-0.00005) mol Co : 0.0003 mol Ba : 1mol Fe : 1 mol P, performing high-speed ball milling in an anhydrous alcohol medium at a rotation speed of 200 r/min for 20 h, drying at 105-120 DEG C to obtain a precursor, placing the precursor obtained via the drying into a high-temperature furnace, and performing high-temperature calcination in a nitrogen atmosphere at 500-750 DEG C for 24 h to obtain the cobalt/barium activated lithium iron phosphate anode material. The doping of a small amount of cobalt/barium is helpful for controlling the morphological form and particle size of product and obtaining stable lithium iron phosphate compound, the crystal lattice of the cobalt/barium activated lithium ironphosphate anode material is activated so as to improve the lithium ion diffusion coefficient, and the initial discharge capacity of the obtained material is up to 160.52 mAh/g; the lithium electrode potential of the charging/discharging platform for the method is about 3.5 V, the initial discharging capacity is over 168 mAh/g, and the capacity after 100 cycles of charging/discharging is attenuated by about 1.2%; and comparing with the non-doped LiFePO4 comparison example, the specific capacity and cycle stability of the obtained material are greatly improved. |
