| titleOfInvention | A kind of preparation method of lithium manganese phosphate material |
| abstract | The present invention relates to a kind of preparation method of lithium manganese phosphate material, step comprises: be dissolved in water by manganese source compound and P source compound, drips precipitation agent, when producing precipitation, stir continuously, after precipitating completely, filter out liquid, washing, obtains precursor powder after drying; By precursor powder and Li source compound in ball grinder, add carbon source, liquid phase ball milling, dry, calcining, after cooling the lithium manganese phosphate material of carbon compound.Present invention employs the precursor made containing manganese compound and phosphorus-containing compound being solubility, make raw material reach the uniformity of molecular level; Precursor mixes with lithium source, carbon source liquid phase ball milling, also substantially increases the uniformity of mixing; Adopt nontoxic absolute ethyl alcohol as precipitation agent, without the need to other auxiliary material, without the need to heating, without the need to precisely controlling precipitation process pH value, easy to operate, low-carbon environment-friendly, absolute ethyl alcohol can also reclaim in rectifying, recycle, technique is simple, is applicable to large-scale commercial and produces. |
