Abstract

The invention discloses a novel ferric phosphate lithium anode material for lithium battery, the ferric potential and phosphate potential are partly substituted simultaneously, with a molecular formula of LiFe<1-x>M<x>P<1-y>S<y>O<4>, M represents sodium element or potassium element, S represents sulfur element, 0<x<=0.5, 0<y<=0.5. The invention also discloses preparation method of the anode material. With the ferric potential, phosphate potential being substituted simultaneously, the ferric phosphate lithium anode material has charge and discharge capacity of high multiplying power and excellent battery circulation performance.
