| titleOfInvention | Lithium ion battery positive electrode material and preparation method and application thereof |
| abstract | The invention relates to a lithium ion battery anode material and a preparation method and application thereof,the anode material is lithium iron phosphate, and the lithium iron phosphate is prepared by the reaction of LiFePO 4 Is designed by components deviating from the stoichiometric formula and has the structural formula of Li 1+x Fe 1‑x PO 4 X is more than 0 and less than or equal to 0.1. The invention provides a deviating LiFePO 4 The electrochemical performance of the lithium iron phosphate is improved by a standard stoichiometric component design method, namely, the lithium is properly excessive and the iron is insufficient, the lithium iron mutual occupation is regulated and controlled to improve the concentration of ferric iron polarons, and further, the lithium iron phosphate (LiFePO) is improved 4 ) The obtained anode material has high purity, a micron structure assembled by nano particles, high tap density, excellent conductivity and electrochemical performance. The lithium iron phosphate anode material is prepared by a sol-gel method, has simple process and lower cost, and is easy to realize large-scale preparation and production. |
