Preparation and Properties of Battery Grade FePO4 from Titanium Dioxide By-Product

Abstract

The battery grade iron phosphate was synthesized with titanium dioxide by-product as iron source, monoammonium phosphate as phosphorus source and hydrogen peroxide as oxidant. The effects of aging time, reaction temperature and stirring speed on the performance of iron phosphate were studied. Used SEM, XRD, ICP to study characterizes the morphology, crystal, particle size and impurity element of FePO 4 . The iron phosphorus ratio of FePO 4 was deter-张明霞
