| titleOfInvention | The preparation method of carbon nano tube modified cathode material of lithium iron phosphate lithium-ion battery |
| abstract | The present invention relates to a kind of preparation method of carbon nano tube modified cathode material of lithium iron phosphate lithium-ion battery, comprise: lithium salts, ferrous salt and the material dissolution containing phosphate anion in anhydrous lower alcohol, are obtained the anhydrous alcohol solution containing lithium ion, ferrous ion and phosphate anion by (1); (2) carbon nanotube is joined in the above-mentioned anhydrous alcohol solution containing lithium ion, ferrous ion and phosphate anion, through ultrasonic and obtain uniform mixture after stirring; (3) crucible filling said mixture is put into encloses container top, the bottom of described encloses container is placed with proper ammonia in advance, and described mixture does not directly contact with ammoniacal liquor, encloses container is heated to 150 ~ 250 DEG C, and is incubated 1 ~ 72 hour; Finally will obtain powder washing, drying, to obtain final product.The carbon nano tube modified ferrous phosphate doping lithium anode material well-crystallized that the present invention prepares, carbon nano tube modified layer thickness are controlled; And preparation process is without the need to calcination processing, energy-conserving and environment-protective. |
