Abstract
A process of fabrication of nanometric lithium transition metal phosphate with the general formula LiMPO, where M denotes a metal ion or mixture of metal ions from a group comprising Fe, Mn, Co, and Ni, particularly lithium iron (II) phosphate, LiFePO, by co-precipitation of nanometric powder from a boiling aqueous solution with the addition of organic liquid containing Li, M, POions which after filtering, washing with water and alcohol, is characterised by the fact that a reducing agent in the amount of 10-100 mol. % in relation to transition metal ions is introduced to the solution containing at least one of the ions selected from a group comprising Li, M, PO; and/or a reducing gas mixture is passed through the solution. At least one of the following agents is applied as a reducing agent: potassium iodide, ammonium thiosulphate, glucose, ascorbic acid, tin(II) chloride.
