NOVELTY - Preparation of ferrous lithium phosphate anode doped by conductive phosphide involves mixing lithium salt, ferrous salt, doping agent and reducer, adding wet milling medium, hypophosphorous acid or hypophosphite, and carbon containing compound or carbon powder, milling the mixture in a ball mill, placing the powder in inert gas or weak reducing atmosphere, and heating and sintering the mixture.    USE - The method is used for preparing ferrous lithium phosphate anode doped by conductive phosphide (claimed) for lithium (ion) cell, polymer cell and super capacitor.    ADVANTAGE - The method is low cost, has wide material sources, simple technique, low energy consumption, forms product with uniform components, excellent discharge property, and good discharge cycle performance in large current.    DETAILED DESCRIPTION - Preparation of ferrous lithium phosphate anode doped by conductive phosphide comprises mixing lithium salt, ferrous salt, doping agent and reducer; adding wet milling medium (1/10-10 times of volume of the mixture); mixing the mixture uniformly; adding hypophosphorous acid or hypophosphite; adding carbon containing compound or carbon powder (1-20 wt.% of ferrous lithium phosphate); milling the mixture in a ball mill for 3-15 hours; drying at 50-105 degrees C in vacuum; placing the powder in inert gas or weak reducing atmosphere; heating mixture to 200-500 degrees C at 0.5-30 degrees C/minute; sintering the mixture for 3-15 hours; cooling the mixture to room temperature to obtain pre-sintered material; adding wet milling medium (1/10-10 times of volume of the material); milling the material using ball mill for 3-15 hours; drying at 50-105 degrees C in vacuum; placing powder in inert gas or weak reducing atmosphere; heating to 500-850 degrees C at 0.5-30 degrees C/minute; and sintering mixture for 3-24 hours to forms ferrous lithium phosphate. When reactant includes hypophosphorous acid, the mole ratio of lithium ion, iron ion, phosphate ion, hypophosphorous acid, and doping agent is x:y:(1-z):k:m, respectively.    k=z-2 multiplied by z;    (m+y)=(x-0.05)-(x+0.5);    x=0.90-1.20;    y=0.80-1.10;and    z=0.001-0.40.
