| 摘要 |
The invention discloses a preparation method of micro/nano structured LiFePO4 compound and the method comprises: mixing Li source, divalent iron source, phosphate, and compound(s) with molten salt effects and calcinating the mixture in an inert atmosphere at a temperature of 550 to 850 DEG C, wherein the compound(s) with molten salt effects can change into molten compound(s) at a calcination temperature. The invention also discloses the applications of the LiFePO4 compound prepared by the above preparation method and the applications of the LiFePO4 compound as lithium ion battery cathode materials. The preparation method of the present invention is simple in operation and can be used to produce products with good electrochemical performance; and moreover the materials required are of low price, therefore the method is convenient for large scale production. |
