| titleOfInvention | Method for preparing lithium ion battery electrode material |
| abstract | The present invention relates to a method for preparing a lithium ion battery electrode material, wherein anhydrous aluminum chloride and sodium chloride are taken and mixed until uniform, heated up and stirred, so as to obtain a molten salt phase; a fused ring compound and an anhydride are taken and mixed until uniform at a molar ratio of 1:1, and are then added into the molten salt phase, mixed until uniform and then roasted; the roasted product is added into a hydrochloric acid solution, stirred for acidolysis for 12 to 48 h, and then suction filtered, so as to obtain a crude product; the crude product is successively refluxed with deionized water, ethanol and toluene once, and is finally dried under a vacuum to obtain the lithium ion battery electrode material. The method of the present invention is simple and easy to operate, is low in cost and green and environmentally friendly, and can be performed in a molten salt system such as NaCl-AlCl3, wherein defects are introduced into the material through binary or polybasic copolycondensation, thus decreasing close packing between molecules, enhancing the electrochemical reactivity of the electrode material, and effectively improving the conductivity of the material by doping a heteroatom. The electrode material has a high energy density, a large specific capacity, and superior rate and cycle performances. |
