Abstract
A method for producing an iron(III)orthophosphate-carbon composite which contains iron(III)orthophosphate of the general formula FePO×nHO (n≦2.5), a carbon source being dispersed in a phosphoric aqueous Feion-containing solution and orthophosphate-carbon composite being precipitated and removed from the aqueous solution when an oxidant is added to the dispersion.
