Abstract:
    This invention relates to one lithium ion battery anode charging ferric phosphate lithium materials and its process method, which processes the front drive by gel-sol method under 30 to 90 degrees by materials of lithium compound, ferric compound and phosphate compound and conductive materials; then heating the front driver in inertia or weak educing atmosphere for analyzing under 100 to 450 degrees; in same atmosphere, heating by 1-30DEG C/min-1 and forging under 450 to 800 degrees for 2 to 24 hours and then culling naturally to get aim product.
