| titleOfInvention | Novel lithium ion battery anode material and preparation method thereof |
| abstract | A provided novel lithium ion battery anode material has the chemical composition of Na3VO4. A preparation method of the novel lithium ion battery anode material comprises the steps: respectively grinding sodium carbonate and ammonium metavanadate to 1200 mesh, and fully mixing sodium carbonate and ammonium metavanadate according to the sodium-to-vanadium molar ratio of 2.5-3:1 to prepare a powder, and calcining the mixed powder at 450 DEG C-600 DEG C for 5-10 h. Sodium carbonate can be replaced by sodium hydroxide, and ammonium metavanadate can be replaced by vanadium pentoxide. The synthetic method is simple, low in equipment requirement and easy to operate. Reactant kinds demanded by synthesis are less, the raw materials are cheap and easy to obtain, and the prepared sample is uniform in dimension and has the average particle size of about 500 nm. The first charge and discharge capacities of Na3VO4 are respectively 363 and 664.3 mAh/g, and the charge and discharge capacities after 50 times of cycles are 205.5 and 205.9 mAh/g. |
