Abstract

A preparation method of a ferrous lithium phosphate material includes the following steps: (1) mixing zinc source, copper source and complexing agent solution, then mixing with iron source and phosphoric acid source, evaporating and dehydrating to obtain a jelly, and then primary sintering the jelly under a protective atmosphere to obtain a solid-phase material; and (2) mixing the solid-phase material prepared in step (1) with a lithium source, grinding and secondary sintering under a protective atmosphere to obtain the ferrous lithium phosphate material.
