| titleOfInvention | Preparation method of carbon-coated porous lithium iron phosphate powder |
| abstract | The invention relates to a preparation method of carbon-coated porous lithium iron phosphate powder, which comprises the following steps: dissolving ferric iron salt in water to prepare a solution, regulating the pH value to 7.0-13.0 with a precipitating agent until Fe2O3.nH2O completely precipitates; separating the precipitate, washing, and acidifying to obtain electropositive Fe2O3.nH2O colloidal particles; adding deionized water into the colloidal particles, adding a surfactant, stirring intensely to obtain a Fe2O3.nH2O colloid; adding water-soluble lithium source, phosphorus source, carbon source and dopant ion compound into the Fe2O3.nH2O colloid, and stirring intensely to form a molecularly uniformly mixed colloid slurry mixture; carrying out spray drying on the slurry to obtain a spherical lithium iron phosphate precursor; and calcining the precursor in a microwave oven in an inert gas protective atmosphere to obtain the carbon-coated spherical porous lithium iron phosphate powder. |
